November 28, 2017 tree for I-S2703, a Big Y match to public genome PGP64

Click here to download our November 28, 2017 tree for I-S2703

This tree shows a new Big Y result for kit 648595. He is part of a large family with colonial American ancestry, which likely goes back to England in the 1600s. According to his STR markers and previous testing for this family, he belongs to the I-L161 "Isles" haplogroup and more specifically the I-S2742 branch (part of Isles-B).  Until now, all S2742+ men in our project were derived for an additional 10 SNPs. But kit 648595 is Y14605- and Y14625-.

At this point, our project has only one known family in this I-S2742* branch. But there is a public genome in the Personal Genome Project (PGP64) who is also S2742+ but Y14605- Y14625-.  According to his Big Y, kit 648595 has approximately 47 private novel variants, and we will search the public sequence of PGP64 for these novel variants. (Update--PGP64 shares almost all of these novel variants, and he's possibly a fairly close male-line cousin to kit 648595)
