A French-Canadian in I-A8742: Updated I-L161 tree

Update August 4, 2018: the link above has been corrected

I-A8742 contains Isles-B5 and some distantly related men, until now all men in I-A8742 have had British/Irish paternal ancestry (mostly English/Scottish). Ken Nordtvedt named the Isles-B5 cluster many years ago but it's not very well defined by STR marker values. Two closely related men in Isles-B5 did the Big Y test several years ago, and they belong to the more specific I-A18001 haplogroup (which FTDNA calls I-BY37256).

More recently, a man with French-Canadian paternal ancestry did Big Y, and he shares 7 SNPs with a man living in England, this branch can be called I-Y55124, but probably FTDNA will call this branch by a different name.
