Cosgriff – The Cosgrove One-Name Study

February 16, 2020February 24, 2020

Am I a Cosgrove or a Cosgrave or a Cosgriff? Can I be all three? (Answer: Yes!)

Introduction

When I first began my genealogical journey, I considered myself a competent researcher with knowledge, skills, and abilities gained from years of academic studies in civilian and military schools as well as experience gained from various military assignments that required researching duties. However, I know that while my research skills would prove useful in my genealogy research, I also recognized I was a novice at genealogy and had much to learn about the field.

One fact that I had to learn was many surnames, such as Cosgrove, have variants and deviants. Its critical to understand the differences between the two forms. According to the Guild of One-Name Studies (https://one-name.org/variants-and-deviants/), a variant is “a name spelling which varies from the primary spelling used by the person’s ancestors and which is:

A name spelling that the person was known to have used, through signature evidence on wills, marriage bonds, etc. or other document originating from the individual concerned, or
A name spelling used by officials on a consistent and persistent basis over a period of years.

The Guild defines a deviant as “another spelling recorded, including cases where the spelling occurs in official records, but only randomly and inconsistently.

Unaware of surname variants and deviants, I began my research into my Cosgrove family line by looking specifically for other “Cosgrove” families. I completely dismissed the possibility that my family could have been known as or used a different surname variant, such as Cosgrave or Cosgriff, at any point in time. Thankfully, I recognized my ignorance early on and did not allow it to deny my ability to ultimately trace my family line back to Limerick City.

Through some much-needed assistance from fellow genealogists, I eventually found the one key document I needed to break down my brick wall: the 1871 Limerick marriage record for my third great-grandparents, John Cosgrove and Teresa Dunn. The record served several research purposes: 1) it brought my Cosgrove family from Boston back to a specific geographic location of origin in Ireland; 2) it listed both John’s and Teresa’s fathers (John’s father’s name was new to me, whereas the listing of Teresa’s father’s name on the record was the same name listed on her 1890 Watertown Death Certificate); and 3) it led me to other much needed records that allowed me to build out both my Cosgrove and Dunn family lines (I also learned at this time that the surname Dunn had a variant as well: Dunne).

As I collected and analyzed various birth, baptism, and death records for John and Teresa’s children, I was struck by the different ways their last name appeared in records: Cosgrove, Cosgrave, and Cosgriff. Out of curiosity, I reviewed other “Cosgrove” families in Limerick and discovered that their last names varied from record to record as well. Some families’ last names were spelled consistently (say Cosgrave) and others were spelled as Cosgrove, Cosgriff, Cosgriffe, and Cosegrave (as examples) across different records. Some were likely variants and others were likely deviants as certain spellings were seen in only one document (such as Cosegrave, a very uncommon spelling of the surname, thus likely a deviant surname).

I was most surprised about was how often a father’s last name may be spelled Cosgriff but the child’s last name was spelled Cosgrove or Cosgrave on the very same birth or baptism record…..or a groom’s name was spelled Cosgrove but one of the father’s or witnesses’ surnames were spelled Cosgriff.

When I transitioned most of my free time from my own genealogy research to setting up and managing our Cosgrove one-name study and its DNA project, I began an out-reach campaign to recruit new members to our study. I made sure to cast my net far and wide by reaching out to Cosgroves, Cosgriffs, Cosgraves, Coskreys, Coskerrys, McCuskers, and McCoskers (and others as well). On more than one occasion, I had some of these people tell me (some adamantly so) that they were “Cosgraves” or “Cosgriffs” and not “Cosgroves” while others told me their Cosgrove families had descended from “Cosgriffs.” I found it simply fascinating how people viewed their surnames both in the present as well as in the past. I also realized I needed to convince some people that our different surnames were actually variants of the others and that they had a place and role in our surname project if they so desired.

What Does My Current Research Reveal?

As part of the surname study, I have been collecting information from various records collections on Cosgrove families. Records to date include birth, marriage, and death records; baptisms; census records; and land and tax records. I have analyzed over 8,000 records to date. While I haven’t conducted any formal statistical analysis of my findings, I can summarize (with a fair degree of confidence) some of the trends I have seen regarding the usage of the Cosgrove surname and its variants:

The spelling for some families’ surnames were very consistent across different types of records.
The spelling for other families’ surnames were wildly inconsistent within and across records collections.
It is not entirely uncommon for families to have more than one surname variant listed for their family names within and across records collections.
Some counties, civil registration districts, and church parishes seem to have a higher occurrence of one form of spelling for the surname (predominately Cosgrove or Cosgrave, and to a lesser extent Cosgriff) than other forms of spelling.
I have even found a couple of instances where surnames were transcribed differently on different genealogy sites found on the same record. For instance, Site A and Site B may have the same baptism record in their Ireland Roman Catholic Baptism Records. The volunteer who transcribed the record for Site A may have spelled the family name as Cosgrove whereas the volunteer from Site B spelled it as Cosgrave. Transcription errors could also explain why some transcriptions have the father’s or mother’s surname spelled differently than the child’s on the same record.

Here are some examples of my findings of birth and baptism records from County Limerick (Chart 1 and 2) as well as an example of a difference in spelling of a witness’ last name between a civil record and church record for the same marriage from County Tipperary (Chart 3):

Last Name	First Name	Birth	Father	Mother
Cosgry	Eugene	3 Mar 1835	John Cosgry	Ellen Tierney
Cosgry	Thomas	5 May 1837	John Cosgry	Ellen Tierney
Cosgry	Hanora	18 Apr 1842	John Cosgry	Ellen Tierney
Cosgriff	Denis	14 Nov 1844	John Cosgriff	Ellen Tierney
Cosgriff	Michael	2 Aug 1847	John Cosgriff	Ellen Tierney

Last Name	First Name	Birth	Father	Mother
Cosgriff	Mary Bridget	6 Feb 1872	John Cosgriff	Teresa Dunn
Cosgrove	Patrick Michael	30 Sep 1873	John Cosgrove	Teresa Dunn
Cosgrave	Catherine	24 May 1875	John Cosgrave	Teresa Dunn
Cosgrove	Matthew	17 Aug 1876	John Cosgrove	Teresa Dunn
Cosgrove	Joseph	15 Mar 1878	John Cosgrove	Teresa Dunn
Cosgrave	Jane	3 Feb 1880	John Cosgrave	Teresa Dunn
Cosgrove	John	6 Feb 1880?	John Cosgrove	Teresa Dunn
Cosgrave	Joseph/John	9 Apr 1881	John Cosgrave	Teresa Dunn
Cosgrave	Teresa Mary	14 Sep 1882	John Cosgrave	Teresa Dunn
Cosgrove	Teresa Mary	16 Sep 1882	John Cosgrove	Teresa Dunn

Groom Name	Bride Name	Wedding Date	Witness #1
Cosgrove	Collins	27 Feb 1867	John Cosgriff
Cosgrove	Collins	24 Feb 1867	John Cosgrove

As you can see in the second chart, the family’s surname appears as Cosgriff, Cosgrove, and Cosgrave across the various birth and baptism records. I know this family well as it is my Cosgrove family from Limerick City. When I first located Mary Bridget’s 1872 birth and baptism records, I initially dismissed the records because I was looking for a Cosgrove family, not a Cosgriff family. Forget that her middle name was different from what I had found in a Boston record along with the fact that the name “Patrick Michael” was the actual given name for my 2^nd great-grandfather, John Patrick Cosgrove. Theresa Mary, the last of the children born in Ireland prior to the family’s immigration to the U.S., had two birth records filed in Limerick City, each with a different surname spelling. To say I was confused by the difference in given names and surnames would be an understatement. Other evidence led me back to this family and once I looked at all of the records objectively, I realized I had found my family. Thankfully, DNA testing of descendants of my 3^rd great-uncles and aunts were shown to be high DNA matches with my uncle and I.

One of the challenges many genealogists and family historians encounter is the listing of different surnames for what appears to be the same ancestor, whether the listings of the surnames are found in family trees made by earlier generations or found in civil and church records or both. In many cases, the experienced researcher will more or less be able to figure out the Robert Cosgrave referenced in a cousin’s family tree or civil record is the Robert Cosgrove found in his or her own family tree. It can be a bit more complicated when we have instances of the surnames McCusker, McOscar, McCosker, and Cosgrove. Some sources exist that suggests these names are variants of one another. I have been in some spirited discussions with people who carry these surnames on the validity of whether or not Cosgrove is a valid surname variant for any of those three names. I have yet to draw my own definitive conclusion on the matter. I do know that I have two Y-DNA groups in my surname project that include two Cosgroves and a McOscar in one…..and four Cosgroves and a McCusker in the other. In other words, the two Cosgroves and the McOscar appear to be distant Y-DNA cousins as are the four Cosgroves and the one McCusker.

The YDNA results could be interpreted in different ways because the sample size is SO SMALL. The YDNA results could indicate a possible surname switch somewhere along the paternal line within each group or we could be looking at two distinct, but genetic related clans in which a Cosgrove Clan and a McCusker/McOscar clan descended from the same paternal ancestor over a 1,000 years ago. A third option is some government and or church authorities deemed the surnames to be valid variants of one another, hence why the same person may be found as a McCusker in one record and a Cosgrove in another. More Y-DNA testing of men who carry these surnames along with additional research across different records collections could help provide stronger evidence that we can use to draw a more definitive conclusion.

Impact of Anglicization of Gaelic Family Names

We have to keep in mind that our distant ancestors once had Gaelic names and it was only in the 1500s and 1600s that the native Irish were mandated to use Anglicized surnames by English authorities. Often times, authorities “gave” the families their new names and these names evolved and changed for reasons sometimes unknown. We also have to keep in mind that some parts of the population in the 1500s, 1600s, and 1700s were not as literate as others, so some of our ancestors may have been entirely dependent upon church officials and civil servants to record their names in records for them, which in itself could explain why surnames appear different from record to record. Thus, the possibility exists a Cosgrove could have once been a McCusker or Cosgrave, but for whatever reason, his surname was written as “Cosgrove” in various public records long enough that the name “stuck” over the generations.

What Does a Genealogist Do When Confronted with this Situation?

My biggest piece of advice is keep open the possibility that your family’s surname may have been spelled differently than what it is today. Of course, if you have a plethora of records dating back to the early to mid-1800s that show your family’s surname was spelled with a high degree of consistency, then you may be able to limit your search for additional records focused on that specific spelling of the family’s surname. However, if you are looking to overcome a brick wall that has existed for quite some time, consider the following:

Your family could have been listed in records under a surname variant(s). When researching records collections both in the country in which you currently reside and, in your family’s native country, ensure you do not purposely ignore records that may list surname variants as family’s last name as opposed to the way your family currently spells its name. You could be overlooking the one or two records you need to break through your brick wall. Remember, depending on where your family lived in Ireland, your Cosgraves could have very well been recorded as Cosgroves or Cosgriffs or Coskreys. In my case, my own family was record as Cosgroves, Cosgraves, and Cosgriffs.
Consider conducting a broader review of records for other Cosgrove families in the same area where your family is suspected or known to have lived. If you are not sure whether your family could have been known by another surname variant(s), consider taking some time to look at records for other Cosgroves in the same parish or civil registration district. As stated earlier, I have noticed trends in certain parishes and registration districts where surname spellings for Cosgrove families were more consistent whereas they were inconsistent in other localities. If you notice a trend that spellings for family names varied in the same area as where you suspect or know your family was from in Ireland, then you may want to explore the possibility your family may have been recorded under a surname variant(s).
Be cautious using other people’s family trees as references. I lost track how many times I have had people tell me that their family trees were built on very strong evidence and generations worth of family records…….only to tell me a few years later they discovered mistakes or discrepancies made by earlier generations of family historians. It happens. We are human and we make mistakes. If you find your “ancestor” listed in another person’s tree under a different surname variant, use caution. Don’t rush to conclude the person’s tree is correct or that this is in fact your ancestor. You still need to conduct research using reliable and credible record sources to draw a reasonable conclusion that your ancestor was listed in records under a surname variant. Don’t go off of an assumption simply out of frustration with your brick wall. Don’t let your frustration and emotion get the best of you!
Assess whether YDNA testing could assist you in your research. Currently, our DNA project includes 19 men who carry one of our recognized surname variants and who have taken a Y-DNA test. We have one genetic group that includes a McCusker and four Cosgroves; a genetic group that includes a Cosgrave and a Coskrey; a genetic group that includes a Cosgrave, Cosgrove, and Cosgriff; and a fourth genetic group that includes two Cosgroves and a McOscar. While it can be reckless to draw definitive conclusions on such a small sample size, initial results do show that surname spellings do vary across genetic families, an insight that is consistent with findings from the records and literature reviews. As more men conduct Y-DNA testing, we may be able to use our DNA evidence to help draw a more definitive conclusion on how frequent surname variants appear among specific Cosgrove families.

Final note

On a final note, genealogists and family historians who have conducted research into our shared surnames’ history have likely read older historical texts such as Rev. Geoffrey Keating’s History of Ireland (specifically Vol III that lists various genealogies of the Ancient Irish Clans), John O’Hart’s Irish Pedigrees, and Rev. Patrick Woulfe’s Irish Names and Surnames. Many of the authors have documented the origins of some of the old Cosgrove families from around the 800-1200 AD period in Ireland in their respective books. Most of them have included the different surnames from which the families were later known by to include their known variants. Thus, the idea that a Cosgrove family may be known by more than one surname variant has existed since at last the mid-1600s when Rev. Keating was known to have written his History of Ireland series.

So for my fellow genealogists and family historians, regardless if your family spells its surname differently today than it did two hundred years ago, your surname IS your family name and any variation in its spelling found in earlier generations is just another fact to include in your family’s history.

Where to get started with your genealogy research: Part III (B)

The following blog posting is the last in a series of recommendations and tips for getting started in your genealogy research with emphasis on researching your Cosgrove family lines.

Part III (A) offered recommendations that included joining discussion boards and social media sites, searching for naturalization records, and understanding naming and immigration patterns to help uncover key information that may enable your ability to link your Cosgrove family line back to a particular place of origin in Ireland.

Part III(B) continues with several additional tips and recommendations. All of our tips and recommendations are meant to supplement, and not replace, the general recommendations you often find in Irish genealogy guides.

6. Cemetery Records.

I have found Cemetery records to be invaluable sources of information. Nearly every cemetery is managed a city or town hall or by a church or temple. Not only can they tell you the exact location of a family member’s grave site, but they may also offer copies of any records that exist (depending on their policies, the additional information could be free or you may need to pay for it).

I had once such instance occur when a cemetery office worker called me after receiving a letter I had sent requesting for the location of several graves in the cemetery. He gave me the plot #s for each grave site and offered to email me additional information that I had not requested, all for free! Included in the information was a record of a family member who was originally interned in a different cemetery a few years earlier whose remains the family had relocated to the family plot at this cemetery….. I likely would never had discovered that her remains had been moved to a different cemetery if the person had not voluntarily given me the additional information!

Also, physically visiting cemeteries may be very help. In some instances, surviving family members of deceased Irish immigrants would sometimes list the county or village in which the deceased was born along with the date of birth. Sometimes parents names were listed on the gravestone too. These may be rare occurrences, but it is something a genealogist and family historian should definitely explore nonetheless!

7. Consider Irish-specific websites to supplement your searches.

There are several genealogy sites based in Ireland that people should consider checking out to see if they may hold records pertinent to their research. One such site I would like to recommend is Rootsireland.ie (http://www.rootsireland.ie). The site, like any other genealogy site, is imperfect and it requires a subscription (if considering this, wait for their periodic sales to buy one!). However, many experts in Irish genealogy consider it to have the best records collections for Irish births, baptisms, marriages, and deaths. I can tell you that the quality of records collections vary significantly from county to county and from parish to parish. For some family lines, I haven’t had any luck finding records…..for my Cosgrove line, I found a ton of very relevant records for Limerick City. Also, the Irish government has established the Irishgenealogy.ie (https://www.irishgenealogy.ie/en/) site. The site is free, but has a much more limited records collection than found on Rootsireland.ie, though exceptions do exist (for instance, Rootsireland has a very limited collection of online records for County Kerry whereas Irishgenealogy.ie has a few more).

The Public Records Office of Northern Ireland (PRONI) has searchable records collection on its website that covers the six Northern counties of Ireland ( https://www.nidirect.gov.uk/information-and-services/public-record-office-northern-ireland-proni/search-archives-online ). If you have ancestors who may have been from the six Northern counties and you could not find their records on either Rootsireland or Irishgenealogy, you may want to look at the PRONI site.

8. Consider British Records Collections

Over the centuries, many native Irish moved to Scotland, England or Wales. Sometimes the moves were temporary before they eventually moved to Australia, New Zealand, Canada, U.S. or another country. Some settled permanently in Britain or spent several years there before moving back to Ireland. Unlike Ireland, the British countries have robust census records too so if you are aware that your Irish ancestors may have re-located to Scotland, England, or Wales, you may be able to find them in one of those countries’ census records. You may also find records for births, marriages, deaths, and baptisms there as well. Also, many native Irish served in the British military during the 1700s, 1800s, and early 1900s, so military service and pension records may prove to be an invaluable source of genealogically relevant information. British land records and court records may prove useful, though I am told access to them may be difficult depending on the person or institution that holds them.

9. Use the Griffith’s Valuation records with caution.

Griffith’s Valuation records are a great census-substitute for the 1830s-1860s time period for Ireland. If you can locate an Irish ancestor among its records, then fantastic! If you can’t, do not despair! If your ancestor did not rent or own land during the time that the data was collected (he year the data collection occurred varies considerably across the 32 counties), then he or she would not appear in the Griffith Valuation records. When I compared Cosgrove marriage, birth, and baptism records to the Cosgrove names in the Griffith’s Valuation records, there are considerably more Cosgrove families that existed according to the vital records collections than Griffith’s Valuation records would suggest. So while Griffith’s Valuation is a great source of information, it is not complete and all encompassing. Its only one source of potential information. If you don’t have any luck finding the family you are looking for, consider other potential sources of information.

10. Do not be shy to mail a letter!

Yes, envelops, stationary, and postage stamps still exist! When I discovered the records collection on Rootsireland.ie that pertained to what I believed was my Cosgrove family, I used the records to build out the family tree to present day. I found several living ancestors (which was a challenging endeavor in itself) for a couple of my 2nd great-grandfather’s siblings. I mailed a letter to one of the living descendants and within a couple of days received a phone call. The cousin was VERY generous with her time to copy some records that belonged to her great-grandfather (the brother to my 2nd great-grandfather). The records she provided were personal records not available on any website, which included some military service records that listed her great-grandfather’s place of birth as Limerick. The records also included the same birth date as I had found in the records from Limerick City. Gaining access to records only in the possession of the family helped contribute to the validation of my research findings.

11. Electoral or Voting Records.

I made an earlier recommendation in Part III (A) about finding your ancestor’s naturalization paperwork to see if he listed a place of origin back in Ireland. Some project members have had a challenging time locating the naturalization paperwork. While I was helping one project member locate the naturalization records, I discovered a voter registration record for her ancestor. The ancestor had immigrated from Ireland to a State on the East Coast and eventually moved to California. The Californian voter’s registration record listed her ancestor’s place of naturalization, which was a specific location back in the State on the East Coast. We couldn’t find the record online, but I suggested she contact archive offices in the area to see if they had a paper copy or a copy on microfiche should could examine. Nonetheless, the voter’s record provided critical information that helped validate some of her earlier assumptions and more than enough information to find the record at a State or Federal archive.

12. DNA testing.

I plan on writing a series of blog postings about the DNA testing for genealogy in the near future. However, in the meantime, I would recommend that a person consider two types of DNA tests available for genealogy: Y-DNA testing and autosomal DNA testing. Ancestry, 23andMe, MyHeritage, and Family Tree Finder are the most reputable testing companies available in my opinion. All offer autosomal DNA testing for genealogy. As a consumer, each company has its pro’s and con’s (I have tested with Ancestry, 23andMe, and LivingDNA and transferred my AncestryDNA test results to Family Tree DNA and MyHeritage). I would offer several pieces of advice when deciding whether to purchase a test from one of them:

Understand why you want to do a DNA test and how you believe the results can contribute to your genealogical research goals.
Always read their Terms of Service BEFORE purchasing a test! Take time to understand how they safeguard and may use your DNA results. Make an informed decision.
Understand the limitations of autosomal DNA testing. DNA you inherit from your ancestors is diluted as it is passed from each generation. For instance, you only inherit (in theory) 50% of a parent’s DNA, 25% from each grand-parent, 12.5%, 6.25% from each 2nd great-grandparent, 3.125% from each 3rd great-grandparent, etc. These are the theoretical averages of inheritance which may vary slightly from person to person (even among siblings). Thus, if your research suggests you and another person may share 4th great-grandparents, the odds are not in your favor that you would share any DNA with that person because the small amount of DNA you each inherit from the shared ancestral couple may not be large enough to match. Second cousins and closer are thought to always share some level of DNA….after that, the odds begin to drop substantially (there is usually a 50% chance 4th cousins who share 3rd great grandparents will share DNA).
Avoid LivingDNA for the time being. While LivingDNA is considered one of the Top 5 testing companies for genealogy, I and others have had very poor results. The company has admitted that they have had issues and are working diligently to fix them. For instance, they have strict matching criteria. So while I have over 30, 000 DNA matches on AncestryDNA, I have ZERO at LivingDNA. Plus, my ethnicity estimates are wildly off the mark, more so than any other company in my opinion. I am hoping that they make improvements soon, as their vision is great, but the results thus far have been very poor in my opinion.

Family Tree DNA, YSEQ, and Full Genomes Corporation (FGC) are all reputable and quality commercial companies that offer Y-DNA testing for genealogy. Only males are eligible for Y-DNA testing because we carry the Y-Chromosome. Y-DNA testing is an option to explore a specific surname line in your family tree. Since males tend to inherit their father’s surname and Y-DNA across generations coupled with the fact that the Y-DNA has a slow mutation rate, you can use the results in an attempt to find other genetic surname matches dating back several hundreds of years, much further back than the limits of autosomal DNA testing and usually further back than many records go. As long as you have a male family member (father, grandfather, uncle, cousin, etc.) alive willing to do a Y-DNA test for a particular surname line (the male must carry the surname as his last name), then Y-DNA testing may be an option worth exploring.

However, Y-DNA testing is without its challenges and disappointments. First of all, while an entry test usually costs around $100, more advanced and beneficial testing options cost several hundreds of dollars, which usually puts them out of the reach of many genealogists. Second, the results are only useful to your genealogical research if other people who share your surname and DNA from a common ancestor have tested as well. While some people will have at least one or more surname matches among their DNA match lists, some people don’t have any. The testing population for Y-DNA tests is significantly smaller (and I mean significantly smaller) than those that have conducted autosomal DNA testing. While I always encourage people to consider Y-DNA testing, I am quick to point out that you may have to wait months or a few years before you have a relevant surname match. If you have a very common Irish name such as Ryan or Walsh, you are likely to have relevant surname matches among your match lists. If you have the Cosgrove surname, you may not have any at the moment. Someone has to test first, so why not you? That is what I told myself and it has worked out well for me as a result!

While YSEQ and FGC are great companies, I tend to recommend Family Tree DNA for Y-DNA testing, mostly because FTDNA sponsors DNA projects for free on its site. You can join as many different types of DNA projects as you want for free as long as you meet the projects’ membership criteria. Each project administrator, who is a fellow DNA tester who has volunteered to set up and manage a DNA project, is allowed to set their own membership criteria. So don’t be surprised if you are either denied membership or you are removed shortly after joining if the project administrator feels you dont meet their criteria. It is what it is. I should know, I have been removed from two projects myself (rolling my eyes). Having said that, I allow anyone to join the Cosgrove surname project as long as their either carry the surname or one of its known variants or if they have a Cosgrove family line in their family tree. I try to be inclusive as opposed to exclusive.

If you already purchased an autosomal DNA test with Ancestry, 23andMe, or MyHeritage, FTDNA will allow you to transfer a copy of the test results over to its site for $19 (you are transfer a copy of the results so in essence you will retain your original results and benefits with the company you tested with and gain access to another list of matches as well as access to the projects at FTDNA).

Conclusion

So that wraps up the three part series on “Where to get started with your genealogy research.” Its taken me 10 months to complete this series, so I apologize for the delays. I spent my Summer and Fall conducting a lot of research for our Cosgrove one-name study. I hope you learned one or two points along the way that will be of help in advancing your research and attaining your goals. If you have any ideas or insight you would like to share, please do so in the comments section below!

Where to get started with your genealogy research: Part III (A)

Introduction

I wrote two previous blog postings on how and where to get started with your genealogy research. The first blog posting stressed the importance of establishing goals for your research endeavors and interviewing living family members as the first two steps in your research journey ( https://cosgrove.one-name.net/?p=20&preview_id=20&preview_nonce=2090fcdf33&preview=true&_thumbnail_id=30 ) . The second blog posting stressed the importance of organizing research efforts and storing the information you collect early on in your research opposed to waiting until you have accumulated an Everest-sized mountain of documents (both physical and digital) ( https://cosgrove.one-name.net/?p=40&preview_id=40&preview_nonce=bb14e07eee&preview=true ).

This third blog posting will focus on some recommendations on different techniques, websites, and records collections that you can use to help you research your Irish family lines. My goal is to provide my readers with ideas and recommendations that differ from, yet complement, the traditional Irish genealogy research techniques you often read about in reputable books and websites.

Researching Irish families is a tricky and often frustrating journey for most genealogists, especially those who descend from Irish immigrants (regardless of where their Irish immigrants eventually settled: US, Canada, Australia, New Zealand, or another country). The reason Irish genealogy research is so tricky and frustrating for those of us who descend from Irish immigrants is most of our Irish ancestors simply listed “Ireland” as their place of origin on most of their adopted countries’ records, such as census records, death certificates, etc. Knowledge regarding the ancestor’s place of origin did not survive past a generation or two after his or her passing. Many of us who identify as descendants of the Irish Diaspora yearn to know, often with great passion, where our Irish ancestors originated. Its not enough for many of us to know that we are of Irish descent…..we want to re-establish our family connections back to a specific county, city, or town where our ancestors lived……and if we are lucky enough, where our distant cousins still reside. This is the “Holy Grail of Irish Genealogy.”

Countless books and websites have been written that specifically address Irish genealogy research methods. They all address the challenges and frustrations I discussed above. However, I feel like many of the methods and recommendations that they offer, which are very similar across the various references themselves, suggest that critical pieces of information on your ancestors’ places of origin can be simply found in vital records, passenger lists, or census records. My experience and those I often engage with suggest that such information is NOT found in these records, though exceptions do exist as they always do. Instead, I have complied a list of techniques, records, and sources that are not often discussed in great detail (or not at all) in books, blogs, and other sites that have been helpful to both fellow project members and myself over the last few years.

Recommendations

The following recommendations are proven techniques that others and I have used to break through our brick walls. Its rare that a single recommendation alone with provide you with the missing piece of information you are struggling to find. Typically, you will need to employ a combination of different methods as well as to collect information from across several different records and sites to provide the irrefutable evidence required to confidently link your Irish ancestor back to a place of origin in Ireland. So lets get started!

Tip #1: Develop a hypothesis to guide your research.

Often times, family historians and genealogists jump head first into their research without taking a moment to develop a hypothesis to help focus and drive their research efforts. A solid, testable hypothesis will help you identify and understand the types of information you need to either prove or disprove the hypothesis. This is critical to help focus your research efforts and help you identify reputable and credible sources of information to examine…..without such focus, its easy for us to expend a significant amount of time, and sometimes money, on aimless research endeavors.

Tip #2. Use forums, discussion boards, and social media to network and collaborate

My own brick wall into my Cosgrove family line was, in my opinion, significant. I examined every record collection I could find on Ancestry.com, American Ancestors, Find My Past, and Family Search. I even had a couple of seasoned researchers visit the Massachusetts State Archives and other records depositories in hope of uncovering records that may not have yet made it onto the internet. They didn’t have any luck.

Then I stumbled upon Family Tree Circles (https://www.familytreecircles.com/). It is a crowdsourcing forum where you can post questions and issues regarding your genealogy research. Fellow members will offer advice and suggestions for you to explore. In my case, a person provided a significant amount of search results using my 3rd great-grandparents’ names as the search criteria. Apparently, they tweaked the search parameters in a way that I had not thought of yet . While I could easily dismiss 98% of the suggested records the person provided due to wrong time periods or locations, there were a small handful of records that I myself had overlooked during my own research that eventually has profound impacts on my ability to break through my brick wall. The small handful of records he or she provided me led to my own discovery of some very critical records. Another bonus about Family Tree Circles is its free to set up an account!

I know many people despise Facebook, but there are several Irish Genealogy Groups on the site that are well managed and helpful. Traditional genealogy groups for most, if not all, of the 32 Counties exist as well as DNA specific groups for all of Ireland and many of the Counties. Word of caution though, the group administrators for the traditional genealogy site have little to no patience for DNA discussions…..they will immediately direct you to join a DNA group if the topic comes up…..make sure you read the group rules because most are tightly enforce!

In addition to county-level groups, there are general Irish genealogy groups as well. It was in one such group that I posted a question, mostly out of frustration, on where I could search for a marriage record for my Cosgrove-Dunn ancestors in Limerick City. I had explained that the record I ordered from the Latter Day Saints was only a marriage index and did not offer any credible information I was hoping it would. A kind gentleman conducted a record search at Rootsireland.ie and found a transcription of my 3rd great-grandparents marriage record……it was the one record that proved instrumental in tearing down my brick wall!

Several of the major genealogy sites, such as Ancestry, have discussion boards available that you can participate in as part of your subscription. Some discussion boards focus on a specific surnames, geographical location, and families. It doesn’t hurt to post a question, though it could be a VERY long time (ie, months and years) before anyone responds to it. I subscribe to the Cosgrove and Clifford discussion boards on Ancestry.com and offer advice whenever I can to people who have posted questions or issues.

Tip #3. Locate your ancestor’s naturalization paperwork!

Personally, I believe it is uncommon to find a census record or vital record (i.e., marriage record of some type) that lists an ancestor’s exact place of birth in Ireland. Often times, you will only see the word “Ireland” in the column for place of birth/origin. If you are lucky, you may see a county listed in the entry. However, I have had much different luck finding a place of origin on naturalization records. Here in the United States, we have two types of naturalization records that genealogists may want to review: Declaration of Intent and the Petition for Naturalization. I have had several ancestors list a county of origin back in Ireland on either one or both types of naturalization records, which allowed me to focus my research efforts into a specific county as opposed to across all of Ireland. I found about 25% of my naturalized ancestors listed their counties of origins on their naturalization records, which is a significantly higher percentage than what I found on other records (less than 5% on census and vital records).

Tip #4. Expand your understanding of immigration patterns.

There is much to learn about immigration patterns. I cannot possibly explain them all in this blog entry. Immigration patterns are important because Irish immigrants tended to live in neighborhoods and cities where family and friends from back in Ireland now lived. If you can determine where your ancestor’s fellow Irish neighbors lived in Ireland, you may have discovered your own ancestor’s place of origin. Plus, it was not uncommon for merchants to recruit Irish natives from specific geographic areas to travel together on chartered ships. In other words, if several immigrants listed County Wexford as their place of origin on the passenger manifests, then there is a possibility that your Irish ancestor(s) came from County Wexford as well. There are a few things to keep in mind when searching for your ancestor’s immigration records:

They could have first arrived in Canada before eventually moving to the United States. Two out of my eight Irish family lines who immigrated to the United States first arrived in Canada and actually lived there for a few years before eventually moving to the States.
Even though they may have lived in a port city, that doesn’t mean that is the city they arrived in. Boston, New York City, Philadelphia, Charleston, and New Orleans were some of the more popular ports where Irish immigrants first arrived. Since my Cosgrove line lived in Boston, I reviewed countless passenger lists from Boston line by line in hopes of finding the specific ship and date they immigrated to the United States. Long story short, they had arrived in New York City and eventually made their way to Boston a few months after their arrival. Painful lesson learned that I am glad to share with others.
Be aware that your ancestor may have had a different name or spelled the name differently than the one he or she used once had lived in the States for a while. It took me two years of research to realize that my 2nd great grandfather, John Patrick Cosgrove, was actually named Patrick Michael Cosgrove on his baptism record from Limerick. Once I made this discovery, I was able to quickly locate his passenger list under Patrick Cosgrove. Included on the passenger list were his parents and several of his siblings….right names and ages…plus the names matched the surviving children who did not die in infancy.
Also, be aware of surname variants. While some families’ surnames were spelled the same way from record to record with some level of consistency, others were not. I have seen countless examples across all of Ireland where the surnames Cosgrove, Cosgrave, Coscar, Cosgriff, and others were used interchangeably from record to record…..and even on the same record (father’s last name was spelled Cosgrove and the child Cosgriff on one of my own family’s birth records!). So while your family may have the last name Cosgrove today, they may have immigrated with the last name Cosgrave, Cosker, or Cosgriff instead!

Tip #5. Don’t be overly reliant upon search engines on popular genealogy sites.

Many people may not be aware how search engines on sites like Ancestry or Find My Past function. Long story short, in order to search for a record, the company itself has to upload an image of the record (lets say a marriage register) to the site. Then, volunteers (people like you and I) will transcribe the information listed in the record into the website’s database. Once saved, the information typed into the database is now searchable. So if the person correctly transcribed my ancestors’ marriage register, the image of the record should appear in the results along with any transcribed information based on the names, locations, and dates I typed in the search fields.

Assuming the record exists first and foremost, and that it is uploaded onto a genealogy site, a successful search will be reliant upon whether the person conducting the transcription 1) could read the penmanship to accurately record the information, 2) did not make any errors such as omissions or spelling errors, and 3) the record itself contained important and accurate information needed to make the transcription possible. For three months I searched for my a death record for one of my Cosgrove family members in Massachusetts. Only five records appeared in the results and I never bothered to look at the actual digital images because the search results listed different names (other than Cosgrove) than what I had typed into the search engine. One day, out of shear frustration and boredom, I clicked one of the records and looked at the image. I was shocked to find out it was the record I had been looking for! The penmanship on the actual record was poor…..while I could make out hand written last name “Cosgrove,” the person who transcribed the record wrote Cognan based on how the writing appeared. In their defense, I could see how they could make the determination it was Cognan and not Cosgrove based on how poorly the name was written on the record. Cognan was the name that came up in the search results, not Cosgrove. Once I was aware of this issue, I did not hesitate to physically review records even if the names on the search results were different than what I had typed in….you never know.

I found a similar issue with city directories. I know I had a particular family line that lived in Bridgewater, MA for decades. However, their names were not appearing in search results in the city directory collections. I started to manually look through the city directories page by page and found them. When I looked at the transcriptions, the record was mislabled…..the volunteer listed them under “Brockton” as opposed to “Bridgewater.” So my specific search criteria of “Kerr”, “1912”, and “Bridgewater” was in theory correct, though failed to appear at all in the search results because their records were transcribed under “Brockton” and not Bridgewater. I found a treasure trove of city directories for multiple family lines once I figured out manual reviews were required.

I also found out that while Ancestry and FamilySearch records collections overlap, that does not mean they have the same identical records in those collections. I had two instances where both sites had two identical passenger lists’ records collections, but one had the record I was looking for pertaining to my Cosgroves and the other site did not. Conversely, the second site had the passenger list for my Cliffords and the first site did not. I only discovered this by manually looking through each individual passenger list for the given month of the families’ respective immigration to the US as opposed to relying on the search results. Since I knew the month and year they immigrated, the manual search was bearable….and very fruitful.

If you are absolutely confident that a record exists for a specific person at a specific time and place, you may either want to physically visit the archive where the record is maintained or conduct a manual search of the record collection on the website (or multiple websites as I have found was needed) as opposed to relying on the site’s search results.

Part III(B) will include several further recommendations to include searching British records collections, cemetery records, and electoral records.

I would love to hear from readers on any recommendations that might be out of the norm that have lead to their successful discoveries of information that helped break down the brick walls in their research.

Welcome!

Welcome to my blog version 2.0. I originally established a blog in February 2018 to complement my work on the Cosgrove Surname Project, a DNA project hosted by Family Tree DNA. Recently, I established a one-name study for the Cosgrove surname at the Guild of One-Name Studies. One of the services and features offered by the Guild is a blog service through Word Press, the same blog site that I used for my earlier blog. Even though the other blog site (Cosgrove Genealogy) is currently “active” until its subscription expires in January 2020, I plan to post all future blogs through the One-Name Study. In addition, I am transferring the previous blogs posted at Cosgrove Genealogy over to this site to avoid readers having to toggle back and forth between sites.

There are several reasons why I started the surname project and the one name study. The reasons have grown and evolved over the last three years.

Reason #1. First, I want to share lessons learned I have collected over my short period of time researching my own Cosgrove family line in hopes of helping fellow genealogists and Cosgrove enthusiasts overcome brick walls in their own genealogical research. I was shocked with how difficult it was to research my Cosgrove family line. Since it is an uncommon surname, though not entirely rare, I thought it would be much easier to research than other family lines, mostly due to the expectation that there would be fewer records that I would have to comb through. Unfortunately, that wasn’t the case. I quickly learned that brick walls are inevitable and they appear much quicker than we would like. And of course, like most Irish immigrants, my Cosgrove ancestors listed only “Ireland” as their place of origin on their U.S. records as opposed to a name of a county or townland, which would have simplified my research efforts. Despite numerous challenges, I used a combination of research techniques and a variety of records collections to break through my brick wall. My first blog series will focus on my lessons learned and research tips that some of you may be able to use to help chip away or even break through your own brick walls.

Reason #2. I want to show fellow genealogists how to use DNA testing to advance their research into their Cosgrove family lines. I have had success using genetic genealogy as a complement to my traditional genealogical research methods. I have personally tested with AncestryDNA, 23andMe, LivingDNA, and Family Tree DNA in recent years. While I had immediate success breaking down brick walls in other family lines, my Cosgrove line was a bit more stubborn. It took over three years of research and targeted DNA testing before I was able to accumulate enough evidence to confidently conclude who my Irish born Cosgrove ancestor was and where he originated from in Ireland. Based on my personal successes and challenges experienced with DNA testing, I will use the blog to help you, in layman’s terms, to design a DNA testing strategy and to apply your test results to further advance your genealogical research. I will also provide a personal review of the DNA testing companies in a future blog posting as well.

Reason #3. I hope to promote my Cosgrove Surname Project on Family Tree DNA (FTDNA). I volunteered to start the Cosgrove Surname Project at FTDNA in April 2016. FTDNA allows members like myself to organize and manage DNA projects on its site…..for free. People can join FTDNA either by purchasing a DNA test directly from the site or transferring a copy of an existing DNA test from another company (23andMe, AncestryDNA, etc) to the site. Once you join FTDNA, there are no subscription fees and you can join as many DNA projects as you like. I will provide a description on the different types of projects that FTDNA hosts and the benefits they provide genealogists in a future blog posting. If you are interested in joining the surname project, please follow this link to join: https://www.familytreedna.com/groups/cosgrove-surname-project/about

I originally created the Cosgrove Surname Project to bring people who have taken a DNA test (Y-DNA and/or autosomal DNA test) together in one location to help connect genetic cousins together. It was meant to serve as a forum to share information on our respective lines and use both traditional genealogical research findings and our DNA results to try to solve our genealogical puzzles. We are a young surname project and currently have 46 members as I write this first blog. Hopefully, we can expand our membership over time. I also created a complementary Facebook group for the surname project as well. I found that some people do not desire to take a commercial DNA test, but still want to participate in the surname project. The Facebook group serves as a forum for people to do so. The surname project on Facebook can be found through the following link: https://www.facebook.com/groups/921428441309363/ .

Reason #4. I have expanded the original purpose of the surname project to include my goal of using our collective Y-DNA results to see if I can connect males who carry the Cosgrove surname (or one of its surname variants) back to the various Cosgrove Clans that populated Ireland prior to the Norman invasion in 1172. My research into the Cosgrove surname and the various ancient Irish genealogies suggests that at least 10 – 12 distinct genetic Cosgrove families existed in Ireland between 400-1200 AD (roughly 2-3 distinct Cosgrove clans in each of the four Irish Provinces of Munster, Leinster, Ulster, and Connacht). In recent years, historians, archaeologists, and genealogists have begun to use Y-DNA test results in an attempt to identify the genetic signature of the various ancient Irish clans. Since Y-DNA is passed only through a male’s paternal line coupled with its slow mutation rate, genetic genealogists can use Y-DNA test results as a bread crumb trail to trace a male’s Y-DNA lineage over hundreds and thousands of years. Some of the Y-DNA mutations also signify a branching point in a male’s paternal line. Since the mutations are passed along through the generations, its highly likely that if two men share those identical mutations, they also share a common paternal ancestor at some point in the past. I hope to refine my research findings into the various Cosgrove clans and use our YDNA results to connect modern Cosgrove lines back to their ancient clan roots.

Reason #5. While my primary focus is on the Irish Cosgrove families, I am aware that there may be an English group of Cosgroves that are genetically distinct from the various Irish Cosgrove families. Overtime, I hope to expand my research and knowledge to include the English Cosgroves both in the DNA project and with the one-name study. If you are descended from an English Cosgrove family line, please join our surname project and help us expand our knowledge about the English version of the surname’s history!

In closing, I’m welcome the opportunity of helping each of my readers learn about their Cosgrove families and to expand our collective knowledge about the Cosgrove surname! Your participation and feedback is always welcomed!
