So, I had one line from a 2nd g.grandmother that produced NO DNA matches through Ancestry.com ThruLines. Her parents I listed were only my best guess. I substituted a new set of parents for her, and all of a sudden, I got 9 DNA matches!
My question is, what, if anything, does this prove? At first, I thought I was on to something. But then I read Ancestry's description of ThruLines, and it basically told me that the predictions were only as good as the trees we've constructed. That sounds like the new DNA matches I got might be misleading.
