I have no biological link to my Father's adoptive parents (honestly, there is absolutely NONE), yet I am being linked through my DNA test to surnames in my tree that have no biological connection. I have to question the whole Ancestry DNA thing.. is it really DNA, or is it NAME matches? My sister and I just laugh at the whole thing and to date (after many so called matches) have been able to connect to only one person (I already knew she was related years ago).
