New branch below I-Y12072, new branch parallel to Driscoll family: 2019-10-17 tree for I-Y12072

This update shows the new I-FT145775 branch, one of the known members is from Germany and the other is American with likely English paternal ancestry. This branch was already known, but now that there are two Big Ys for this branch it can be named. The two men share at least 24 additional SNPs that are currently equivalent to FT145775.

This tree shows a new branch immediately below I-A13665. Because only one man is known to belong to this branch, we can't confirm the SNPs and we call this branch I-A13665*.  The I-A13665* man has paternal ancestry from central France.

All other known men in I-A13665 belong to the more specific I-Y31631 branch, and they all are named Driscoll or O'Driscoll, or they very likely have a paternal ancestor named Driscoll at some point in the past. Y31631 is in a region which is very similar (97%) to other two regions in the Y chromosome, it can not be tested as an individual SNP.

FTDNA shows Y31631 as equivalent to A13665, this is incorrect.

FTDNA shows Y85926 as equivalent to the downstream SNP A14539, this is incorrect. This draft tree shows Y85926 in the correct position: equivalent to A13665.
