I have my Nancy Wheeldon tree open to the public. I used to have a couple of other trees public, but then switched to private. But most of my paternal relatives are also on my Nancy Wheeldon tree. I picked her as a half way point along the line. She is not otherwise of special significance. I know little about her daughter, which was a dead end for quite a while. Anyway, the main idea is to trace my U5b2 mtDNA haplotype back as far as possible. It dead ends in NC. But I have a rare HVR1+HVR2 match in earliest Massachusetts.
