A major new branch of I-L1498: updated I-L161 tree

Click here to download our June 13, 2018 tree for I-L161

This tree shows two updates:

1) There is a new German-American Big Y result. He is A10029+ and he is ancestral for approximately 30 SNPs that were formerly considered equivalent to A10029, for example he is A10028-. He has only one name on his Y-DNA match list, and this match has a German name. This new I-A10029* branch has a MRCA of 6700 years or greater with all other known branches.

2) There is a new result in I-A10036 (Isles-B3). He is closely related to the large American Hale family, but it's unclear to me if he has a Hale ancestor, or if the common ancestor was before the era of surnames (he is not named Hale)

A new branch for Isles-B4 which contains a sample from P. Hallast study: updated I-S2703 tree

Click here to download our June 15, 2018 tree for I-S2703

This tree shows two updates:

1) There is a new branch called I-PH151. This branch is exactly equivalent to the Isles-B4 cluster, which is defined by some distinctive STR marker values, for example DYS388=11. This branch is rare and mostly found in southern England, but the Pille Hallast study (2014, Estonia Biocentre) found a sample (ire-94) in Ireland that shares the STR marker values and which has several SNPs named PH151 etc, these SNPs are shared by an Isles-B4 Big Y result. Another Isles-B4 Big Y is in progress, this one is a more distant match to ire-94

2) There is too much information on the I-S2703 tree, and we have created a new tree for I-Y14612 (click here). I-Y14612 contains the Isles-B1 cluster which is maybe entirely English in origin, but it also contains some branches from elsewhere in Europe, especially Sweden

A second I-S20602* sample and a Greek Y18331+ A2512- branch: updated I-CTS10228 tree

Click here to download our June 3, 2018 tree for I-CTS10228

For several years we have known about 5 branches of the I-S20602 haplogroup:
I-A2512
I-Z17855
I-Y4460
I-S17250
and an unnamed I-S20602* branch represented by a single Big Y result for a man with ancestry from southern Poland.

This update shows a 6th branch, another I-S20602* man who has ancestry from Germany. He doesn't share any variants below S10602 with the Polish-ancestry man, or with any of the other 4 branches.

Until recently, A2512, Y18331 and Y18332 were considered to be equivalent SNPs. But according to a recent Big Y, a man with Greek paternal ancestry is Y18331+ but A2512-. His result for Y18332 is currently unknown. So now I-Y18331 is one of the 6 basic branches of I-S20602, and I-A2512 is a subbranch of I-Y18331.

(There are other additions to the tree, shown in red)
