Hallo! I once saw here at G2G a link to a site offering guidelines for searching for birth fathers (at least the familes that they came from) through family tree and DNA research. I have lost this link. Of us seven half-brothers, only two of us know who our father was. I'd like to help my brothers with their research, if i can. We have all tested at FTDNA, except for one, who is deceased. Thank you.
