A new branch, I-Y32666,  with an estimated TMRCA of 225 ybp, has been created under I-Y7277  on the I1 haplogroup tree.

Now all we have to do is convince a few more of the matching Fairbairn kits, or an Elliot or two, to similarly test, to see how far back from that the Fairbairns and their matching Elliots (a very small subset of that surname project) diverged, or were still together for that matter!
