Collaboration and communication are essential in Y-DNA testing, including within a Group Project and among administrators. Margaret O’Shea-Jordan gives an overview of how DNA testing and Group Projects have helped her achieve her goals.
I got into using DNA as a genealogical tool when I was trying to find my late father’s birth parents. I didn’t have much information to go on; therefore, using science to find his family of origin appealed to me. In early 2003, I ordered a kit from FamilyTreeDNA for my father (surname O’Shea) to do a Y-chromosome DNA (Y-DNA) test.
I was aware that one other man with the same surname had also tested just ahead of my father. Over the next few months, several men with the O’Shea surname or a variant of the surname did a Y-DNA test through FamilyTreeDNA.
It was time to set up a project to keep track of results, learn more, and share this information with project members.
The O’Shea Y-DNA Project
We administrators of the O’Shea yDNA Project were DNA enthusiasts who wanted to learn more about the origin of the O’Shea surname and how our patrilineal lines are connected to each other. It was always exciting to send off another DNA sample to FamilyTreeDNA, but it was tortuous waiting for the results. It still is! Communicating with project members is a priority, and helping them understand what their results mean is vital.
In the early years of the project, we actively recruited O’Sheas from areas in Kerry, Cork, Tipperary, and Kilkenny. We felt it was essential to have Y-DNA from people who still lived in areas of Ireland where the O’Shea surname has been present for hundreds of years.
Sharing Ideas and Learning
Collaboration is extremely important in Y-DNA testing. This includes collaboration within a Group Project and among Group Project Administrators. Y-DNA haplogroups, Y-DNA geographic groups, and surname groups all contribute to our collective learning. Online communities share ideas and new achievements gleaned from Y-DNA.
FamilyTreeDNA sent a representative to the Clans of Ireland meeting in Mallow, Co. Cork, in 2005 to talk about DNA testing.
This was exciting to the administrators of the O’Shea Surname Project, and we were delighted to get the opportunity to meet the representative afterwards and discuss Y-DNA.
As the O’Shea yDNA Project grew, we kept up to date with what was going on in the DNA world, especially developments relating to Irish Y-DNA. In Ireland, in the mid-2000s, several Y-DNA research papers were published by the Genetics Department, Trinity College (TCD), Dublin. In 2010, the first Irish genome was sequenced by a team from University College, Dublin (UCD).
How SNP Testing Helped Our Results
In the 2000s, we administrators had been mainly using Y-STRs as we tried to predict which Y-DNA haplogroups our members’ Y-DNA belonged to. As SNP testing became more available, we used SNPs to figure out where the O’Shea Y-DNA fit on the Y-DNA haplotree. A Y-DNA results chart is one of the basic tools provided by FamilyTreeDNA. This means that administrators can group people as they see fit.
We established several groupings based on mutational differences in Y-STRs and added SNP results as they became available. It was exciting to find a new SNP that confirmed the groupings we had created based on Y-STRs. We were learning that men who carried the O’Shea surname could be grouped into several disparate groupings that had not been connected on the male line for thousands of years.
Family Finder’s Role in Our Research
In 2010, FamilyTreeDNA introduced “Family Finder,” their autosomal DNA test. This expanded DNA testing enormously. I used this successfully in my own quest to find my father’s close male line by asking his closest Y-DNA matches to do an autosomal test in addition to the Y-DNA test they had already done. Having their original samples stored in the lab in Houston helped with this.
Using autosomal DNA and Y-DNA enabled me to narrow the possibilities down to the point where I could focus on a specific family line and ultimately identify my father’s biological father.
Ancient DNA Contributes to Our Research
I remember attending a Bioconnect Ireland meeting in Dublin in early 2013, where Professor Daniel Bradley (Genetics Dept., TCD) mentioned ancient DNA in his presentation. In recent years, ancient DNA has become an integral part of the genetic genealogy world, and FamilyTreeDNA incorporates results from ancient Y-DNA samples into its Big Y timeline.
FamilyTreeDNA Conference
Later, in 2013, the first Genetic Genealogy Ireland event was held in Dublin.
This event was sponsored by FamilyTreeDNA and was a great way for Irish Project administrators to meet each other and chat with visitors from the USA and other places.
Big Y Testing
In 2014, the Big Y test was rolled out by FamilyTreeDNA. Next generation sequencing (NGS) was used, and this was a game changer. We could now let FamilyTreeDNA do the heavy lifting to find new branches of the Y-DNA haplotree. It was an eye opener as the Y-DNA haplotree became more and more detailed.
Additional Group Projects
In 2006, I was asked to join two others as administrators of the newly formed Ireland yDNA Project.
This project was set up to take Y-DNA results for men with Irish patrilineal lineages. It caters to all Irish surnames.
Y-DNA Group Projects
Men who had tested with the Genographic Project could also transfer their Y-DNA data to FamilyTreeDNA. Having an Irish Y-DNA project for them to join was seen as important, especially when there weren’t very many Irish surname projects in existence at the time. The Ireland yDNA Project became very popular, growing to over 10,000 members.
Y-DNA is shining a light on the origins and development of surnames in Ireland and the wider context of the migrations of ancient peoples to the country.
I was an administrator of the Ireland yDNA Project for over 16 years, but in 2022 I decided to step back and concentrate on helping smaller surname projects that focus on the south of Ireland.
So, as well as the O’Shea yDNA Project, I am involved with the Meaney, Lucey, and Kelleher surname Group Projects. I am eager to utilize the Big Y-700 test in these projects in order to learn more about these surnames.
Autosomal Group Projects
Some years ago, I set up a NW Co. Cork Family Finder Project that covers the Millstreet-Macroom-Banteer area of Co. Cork, an area that relates to the paternal side of my own family.
People who can trace one or more ancestral lines back to this area can join if they have done autosomal DNA testing and see if they match others within the project. They can share family information, compare family trees, and try to find common ancestry.
I would like to finish by saying that Irish surname Group Projects are benefiting hugely from the Big Y-700 test and reports, which greatly aid the analysis of results.

Hello,
My Grandmother was called Catherine O’Shea born in Tralee born in 1886. Her Father was Daniel O’Shea who married Margaret Moriarty in 1875.
I am keen to take a DNA test. I also belong to the Moffats which are also on the FTDNA site.
I am assuming my DNA would show both family trees?
