Click here to download our January 11, 2017 draft tree for I-Y12072
In our last update, we mentioned the first known man with PF4135+ and Y11772-, A11374- and A13665-, Y31631- results.
Now a second man has completed a Big Y and he has the same results. The two man share one additional SNP called FGC39003. (This SNP was found in 2014, it occurred independently in haplogroup G).
We can now name a fourth branch of I-PF4135: I-FGC39003. The two known families in I-FGC39003 aren't closely related based on the number of variants unique to each family. One of the families is from southern County Tipperary, Ireland, which is consistent with an overall origin of the I-PF4135 haplogroup in the County Cork area of Ireland.
