Click here to download our July 17, 2018 tree for I-S2703
This tree shows a new I-Y140515* branch, based on a single Big Y for a man with Mexican paternal ancestry. He is a distant STR marker match to a man from Chile.
This tree also shows a more specific I-S2624 branch which contains two Big Ys for an American family that is supposed to have ancestry from England in the 1600s. This branch also contains someone in the Public Genomes Project, that's why many of these SNPs were given S series SNP names many years ago. Click here for my earlier post with more details.
The Mexican man has 18 private variants that weren't found in the I-S2624 Big Ys (these variants aren't shown on the tree). Based on this number, we would estimate that the common ancestor of I-Y140515 lived a little more than 2000 years ago. But the I-S2624 Big Ys share 35 variants that weren't found in the Mexican man's Big Y. This points to a more ancient common ancestor of I-Y1450515. The Y111 markers for the two groups are very different, so maybe the common ancestor lived several thousand years ago.
