Another British branch of I-M26: updated I-L160 tree

Click here to download our February 19, 2018 draft tree for I-L160

I-M26 represents less than 1% of men in Great Britain and Ireland. Some of the British/Irish I-M26 men have paternal lines which must have arrived in Britain/Ireland in the last 2000 years. For example, some British men belong to I-Z113 which is strongly Spanish and which had a common ancestor who lived 1750 years ago according to YFull's calculation.

But several other branches of I-M26 are strictly British/Irish and had a common ancestor who lived 4,000 or more years ago, likely in Britain or Ireland.

Our updated I-L160 tree shows an updated I-A19487 branch with a newly defined I-A19490 subbranch. There are three Big Ys for I-A19487, but they represent a large cluster of related families, all are from Scotland or England. This branch has no known Irish representatives, except for families which arrived in Ireland in the last 500 years from England or Scotland.

  1. With a terminal SNP Y89254, is this likely to be an additional branch off PF4189 for Falconer, kit 392665?

  2. I didn't see this question until today...Falconer is Y89254+ but you can see on the tree that the two men in the I-A19490 branch are also Y89254+. So, yes, Falconer belongs to the I-Y89254 branch. But eventually some closer relatives (the Barclays for example) will do a Big Y, and then we will learn of a new SNP that will be more specific to the Falconer/Barclay branch. I posted a new I-L160 tree today, but I don't think there are any updates for these branches.
