Click here to download our February 7, 2018 draft tree for I-L233 "Western"
Near the bottom of the tree, you can see the I-F25958 branch and its new subbranch, I-Y106756 , is shown in red. The I-F25958 branch contains the Scottish-origin Lindsey family, and some men of other surnames who probably had a Lindsey ancestor a few hundred years ago. The most recent common ancestor of the entire Lindsey was many hundreds of years ago, so it's not surprising that we can find a SNP like Y106756 specific to one branch of the family.
Near the top of the tree, you can see the I-BY33210 branch and its new subbranch, I-Y131236, is shown in red. The I-BY33210 contains the colonial American Terry family, who probably share a common paternal ancestor in Virginia or another colony in the 1600s or 1700s. This is a much more recent common ancestor than the Lindseys' ancestor. But fortunately, thanks to three completed Big Ys, we found the Y131236 SNP which is specific to one branch of the Terry family.
Both families have multiple Big Ys still in progress.
