The yDNA results are identified by haplogroup (e.g. R1b1b2). Since R1b1b2 is the haplogroup of the majority of members of the O'Shea yDNA Project, it is further subdivided, into groups, to help identify distinct clusters within the haplogroup. Modal haplotypes are given for all groups and markers which show mutations from the group modal are coloured to indicate this.
Note each of the R1b1b2 groups contains Irish born participants who are certain of their immediate ancestry. yDNA results for these members are intended to be benchmarks for O'Sheas who may not know their ancestor's origins.
Note our yDNA results spreadsheet includes some results from people who tested with a company other than FTDNA. We would like to hear from others who may have tested with companies other than FTDNA.
Certain markers, known to mutate at a slow/medium rate can be identified as signature markers for sub-groups in the Kerry Group, Cork Group and Tipperary/Kilkenny Group.
In general, marker values are coloured where the allele value differs from the most common value (modal) for a group and in some instances these markers indicate sub-groups.
The spreadsheet shows by column the Ysearch ID for those whose results are in Ysearch, the earliest ancestor and the full 67 markers for those members who have achieved this level of testing.
The main Kerry Group (Kerry 1) ( shows two distinctive patterns of results, based on DYS391 and DYS GATA H4. Three members of the main Kerry Group have done Deep Clade tests and three are reported to be R1b1b2a1b5 (L21+). Many members of the main Kerry Group are in the L21+ 11_13 Combo Project which caters for people who are L21+ and who have a value of 11 or more on DYS406s1 and a value of 13 or more on DYS617. The 11_13 Combo Project is actively looking at the various clusters which are 11_13.
A second Kerry Group (Kerry 2) which shows results for one O'Shea from Dingle and an O'Shea from Beaufort, Killarney. These two O'Sheas, who were not known to be relatives prior to testing are a genetic distance of 5 at 37 markers. Their results are quite distinctively different from the main Kerry Group.

The NW Cork/Clondrohid Group is Group 2. Two members have done a Deep Clade test for this group and are both reported to be R1b1b2a1b5 (L21+). One member who is confirmed to be L21+ did the L159.2 SNP which is a SNP downstream of the L21 SNP. He was negative on it but it was an effort to see if the Cork/Clondrohid Group could be defined by this SNP. There was a "sporting chance" that it would be positive. He also did a DYS464X test and represents this group in the 464ccgg Project.
Note, that several members of the Cork/Clondrohid Group are using advanced markers: DYF399X and DYS710 to help filter close matches at 37 markers. Here is a link to these results: Advanced Marker Results

The Tipperary/Kilkenny Group is called Group 3. Two members of this group have done Deep Clade tests and are both reported to be R1b1b2a1b5 (L21+). This Group has a value of 13 at DYS426 which is off modal for R1b1b2. Off modal values for other markers are also present leading to this group being part of a bigger cluster called the 4th Irish/Continental Modal haplotpe (Ysearch ID UWM64). Further investigations are needed to learn more about this cluster. Some members have upgraded to 67 markers. James O'Shea has set up a website for the 4th Irish/Continental cluster.

Other groupings of R1b1b2 members is an effort to identify affiliations such as belonging to the "South Irish" cluster. The "South Irish" cluster includes Eoghanacht surnames like O'Sullivan, O'Connell, O'Donoghue etc.
The "Unassigned Group" is for members who are R1b1b2 but who do not yet fit any of our classifications.
The Phylogenetic Diagram (below) shows the R1b1b members of the O'Shea yDNA Project (diagram courtesy of Fluxus Engineering).
You can see the three main groups: Group 1 - Kerry, Group 2 - NW Cork, Group 3 - Tipperary/Kilkenny.
Family Tree DNA Analysis of yDNA Results
An analysis of 25 marker matches is provided by FTDNA: 25 Marker Match Analysis
An analysis of 37 marker matches is provided by FTDNA: 37 Marker Match Analysis
An analysis of 67 marker matches is provided by FTDNA: 67 Marker Match Analysis
A tutorial on understanding the results is at Tutorial on Understanding the yDNA results from FTDNA
The yDNA results can be compared to others at YSearch. Ysearch is very useful, so make sure you upload your results to it to compare results with others. This is particularly interesting to see how your results compare with people in your yDNA Project and others who are not in your own project or who are using a different testing company.
Haplogroups
Anthropologists classify the Y-chromosome into branches called Haplogroups or clades. Letters, such as J, Q, R etc classify Y-chromosome haplogroups on the yHaplotree. Haplogroups are subdivided into smaller groups or clades. For example, Haplogroup R is divided into "R1a" and "R1b" and R1b is further divided into R1b1 and so on.
Deep Clade and SNP Testing
When you test your yDNA using the standard y-STR markers, your Haplogroup can usually be predicted. Once your Haplogroup is predicted, you can then use a
Deep Clade Haplogroup Test to identify the SNP mutations that occurred over thousands of years ago, to help find a detailed location, on the Y-chromosome tree (yHaplotree) for your yDNA.
Family Tree DNA's "Deep Clade Haplogroup" tests relevant known SNPs to help to classify the haplogroup into a subclade.
"The purpose of the Deep Clade test is to confirm your haplogroup assignment and determine where your lineage fits within that haplogroup's tree."
So, if you start off knowing that your haplogroup designation is predicted to be R1b1b2, you could learn from a Deep Clade test that it is confirmed to be R1b1b2a1a or R1b1b2a1b5b etc. which is a much greater refinement. It gives you more knowledge of your deep ancestry going back thousands of years.
A Deep Clade test can also confirm a haplogroup where it had not been successfully predicted. Research into subdividing haplogroups into subclades by further SNP testing is ongoing, with the ongoing discovery of SNPS which define subclades.
The search is on for signature SNPs which will be used to define various Irish surname groups. Many Irish surnames are L21+ and there are SNPs being discovered, downstream of this SNP which may define Irish surname clusters. The Ui Neill has M222 SNP downstream of L21, the Irish Type III (Dalcassian) has the L226 SNP also downstream of L21 while the Eoghanacht do not yet have a SNP downstream of L21. The Leinster Cluster are also using ySTR markers and SNP testing to analyse this group. All this research is exploring the ancient history of the Irish and the veracity of the written records using DNA.
Family Tree DNA lists the Advanced SNP descriptions.
Currently there is no uniform nomenclature for naming subclades within haplogroups. Here are links to three main classifications:
