Yellow pin = Family Finder only tester. Group 1 = green pin. Group 2 = turquoise pin. Group 4 = deep blue. Group 5 = red pin. Unmatched/ungrouped = purple pin. Testers who haven't identified their exact ancestral locations are shown in approximate locations. See group definitions below.

The following table divides participants into groups depending on what we know about their haplogroups and haplotypes.

See A Basic Guide to Y-DNA Testing for Ireland Projects (PDF) for further explanations of these groups as well as the links above plus Further Reading for more scientific explanations.

Y-DNA Test Participants

Participants are grouped with their matches within the Irish haplotype category which they best match based on Jim Cullen's Haplogroup Predictor and also based on the terminal SNPs of their matches within FTDNA. Kits within a group match one or more kits within the same group.

The Participants by Haplotype page has been discontinued. Project subgroups are being allocated their own pages. Pages have been created for Groups 2, 4, and 5. Additional pages will be created as more members enroll in the project and more groups are identified.

Results less than 37 markers are not included in our results / analysis.
