This tree shows a new branch called I-Y137889, it's one of three branches below I-PF4088.

I-Y137889 is uncommon, the known members have Spanish ancestry, or they are Americans with likely British ancestry. They all share some distinctive marker values: DYS447=20 or lower, and DYS425=10.

The other two branches of I-PF4088 are called I-A17273 and I-CTS1758. For reasons of legibility, we have created a new draft tree specific to I-A17273 (click here)    I-CTS1758 is a very large group and it contains I-Z102, I-PF4189 and many other branches.
