Thanks for the feedback, Tom. The eBook only covers about half of the posts – maybe I can get the other half in Vol 2. Jim

I say there appears to be a connection, and that based on 7-9cM segments, it could be back many generations. With this data, I cannot be any more precise – I don’t think anyone can. Jim

Veronica, Taking a little breather, but already comparing all the blog posts to cull out the ones that were covered in Vol 1. At the top of the list for Vol 2 will be a Chapter on Bio-Ancestors and a Chapter on Walking the Clusters Back (which tie into the Bio Ancestry effort).
Thanks to you, specifically, for all your excellent feedback on the drafts.
Sincerely, Jim

Many thanks and congratulations Jim for your research on this subject over the years. Other family researchers will find it interesting and invaluable. Thanks again
