Guild of One-Name Studies
One-name studies, Genealogy
At present, the Foad Surname DNA Project is the main thrust of this one name study. We have tested the Y-DNA of 8 male FOAD and found that 6 of them match each other fairly closely on 67 STR markers. The genealogy of a 7th participant indicated that he was related to several of the other members, while the DNA test proved otherwise (possibly due to the occurrence of an NPE or misattributed paternity). We interpret these results as tending to confirm (though not proving) our Single Founder Hypothesis. The six matching participants all belong to Haplogroup I1a2a1a, a newly proposed subgroup which is positive for polymorphisms M253, Z58, Z59, Z60, and Z140. In additional, several of our members have already tested positive for F2642 which is apparently downstream from Z140, though not yet officially recognized by ISOGG. This project is still small and all of our 'conclusions' are tentative.
We have also tested one FOAT participant who, so far, does not match any of the FOADs. Obviously, we need to test more FOADs and FOATs.
