Working on following up with the recent matches at 23andMe and adding them to my atDNA spreadsheets for tracking.
Dad's DNA match with cousin Sarah is predicted to be 3rd to 6th cousin, a pretty distant match. The percentage shared is only 0.23% on two segments. However, Sarah and I share no DNA.
I do not see any surnames on her list that match, and she did not share a family tree to compare. Will have to triangulate and hope that we can find a match at a later date.
