A new continental European branch: 2020-08-23 draft tree for I-Y4252

 Click here to download our 2020-08-23 draft tree for I-Y4252


This update shows a new branch called I-ZS9184, it contains two Big Y-700 samples, one from the Netherlands and one with paternal ancestry from Hannover, Germany. These Big Ys were completed several months ago, but FTDNA added this branch very recently. ZS9184 occurs in a Y chromosome region that is sometimes considered unsuitable for phylogeny.

This update also shows a new branch called I-FT355585, it's part of the "Western-Isles" cluster (I-BY63871).

And this update shows a new branch called I-FT303575 and the more specific I-FT353020 branch.

More samples for some Irish families: 2020-07-15 tree for I-Y4665 (Isles-D2)

Click here to download our 2020-07-15 tree for I-Y4665 (Isles-D2)

This tree shows a third Big Y sample for a Flynn family and a fifth Big Y sample for a Morrissey family.  I-Y4665 is very typical of Ireland, especially central-western Ireland. The I-Y4665 Flynn family is one of dozens of Flynn families in Ireland, and probably many Flynn families in other haplogroups are much larger.  There are also several Morrissey families but maybe the I-Y4665 Morrissey family is the largest Morrissey family.
