8 SNPs define a Manx family: Updated I-Y12072 tree

Click here to download our latest I-Y12072 tree

Most of I-Y12072 belongs to the more specific I-PF4135 "Isles-A" haplogroup, which seems to have originated in County Cork, Ireland. But there are some families which left Cork more than 1000 years ago and flourished in Scotland, the Isle of Man, and probably England.

Two men from the same family from the Isle of Man have completed Big Y, and they share 8 SNPs, and this update shows their new I-Y79838 branch. There is another family from the Isle of man which shares many STR markers, and probably they also share many of the 8 SNPs.

As you can see on the tree, the closest relative of the I-Y79838 branch is the I-A19478 branch which is represented by a man with County Cork paternal ancestry. There are many families with Cork ancestry found in all parts of the I-PF4135 haplotree.
