a genealogist's sketchbook

I just uploaded a new version of my e-book An American Taylor Family, which incorporates some revisions which have been on my ‘to-do’ list for over a year! This post is not just self-congratulatory, however, it’s to draw attention (my own as well as anyone’s who might read this) to a feature which I haven’t seen elsewhere. In 2010 five descendants of Simon2 Taylor established a Y-DNA genetic profile for him as our MRCA. I’ve blogged the results here and they’ve made it onto the ‘Taylor’ surname project site at ftdna.com. What hadn’t happened until now was incorporating this information into a traditional Register-style compiled genealogy. Now there’s a presentation of the DNA data in the introduction to the book, but also, each head-of-household in the direct ancestry of a tested individual (who has therefore been confirmed to belong, biologically, to this family) is indicated with a little double-helix icon next to his entry:

So: has anyone else done this, or seen it, in a compiled genealogy? I should ask Alvy Ray Smith, who has put together big Riggs genealogies and done good Y-DNA work on them too.
