More details about the I-Z27025 branch: updated I-L160 tree

Update August 6, 2018: the link above has been corrected. Note: if you download the tree at the link above, you will see the date 2018-07-02 on the upper left corner of the tree, but I think this tree was prepared on 2018-07-15

Our I-L160 tree became too large and we moved the more specific I-CTS11338 branch to a tree of its own, click here for more information.

This update shows additional SNP information for the I-CTS11338 branch.

This update gives more details about the I-Z27025 branch. It contains 5 men with recent Sardinian ancestry, four of these are anonymous samples from the Francalacci (2013) study, and one is a member of our FTDNA project. This branch also contains three American families: one believes he has Irish ancestry. A second family is a distant STR match and has ancestry from Belgium. The third family is more distantly related, it contains several members and is probably English origin.

The three American families share distinctive STR marker values with our Sardinian project member, so we expected that this was one of the small Sardinian I-M26 branches in Francalacci's study, and we sponsored a Big Y for one of our American members with our General Fund money.

The American shares 11 SNPs with Francalacci's samples 315-318. Very likely the other two American families share all of these SNPs. Our Sardinian project member very likely shares all of these, and maybe he shares additional SNPs with some or all of samples 315-318.

Our American project member has 37 private SNPs that weren't found in the Sardinian samples, so any common ancestor with the Sardinian men would have lived more than 4000 years ago.
