The M26-"France" group with DYS391=9 is complicated: Updated I-Y11222 tree

More than 10 years ago, Ken Nordtvedt identified a distinctive cluster within M26 that was characterized by the distinctive marker value DYS391=9 (almost everyone in I-M26 has DYS391=10). When 37 and 67 marker tests became more common we learned that this cluster has additional characteristic marker values, especially DYS425=0. He called this cluster M26-"France".

After a few Big Ys and individual SNP tests, we saw this pattern:

I-M26 people with DYS391=10, and DYS425=0 belonged to the I-Y14720 haplogroup

And I-M26 people with DYS391=9, and DYS425=0 belonged to I-Y14720, and also belonged to the more specific I-Y15460 haplogroup.

But now we have a Big Y for someone with DYS391=9, and DYS425=0, and he is Y14720+  Y15460-. He shares 4 SNPs with two previous Big Ys. The new I-Y63435 branch is shown in red on the updated haplotree.

********
Most I-Y14720 men have DYS391=9 and are Y15460+. But this new result shows us that we can't always predict Y15460 results: some I-Y14720 men who have DYS391=9 are Y15460- and Y63435+.
