Previous Y-DNA testing

The Thayer Families Project Group: G1 - Thomas currently has fifteen related males, thirteen claiming patrilineal (all male line) descent from Thomas1Thayer. Some have done at least some level of Y-SNP testing with the family falling under: P312>Z290>L21>DF63

NGS/WGS testing

Two individuals in the project have taken the Big Y-700 test which revealed they fall under R-L21>S552>DF63>FT91736>BY28644>BY42307.
