Ancestry/Genealogy

I talked my cousin who is a directly male line descendant into getting his DNA testing. One of the respondents was a young man who is looking for his biological father who was a sperm donor. The young man has to be a blood relative since the match was very close, but could be third or fourth cousin.

Since the ancestor I was trying to trace had ten children who lived to have children, one of which had 24 children, there are actually a lot of possibilities for that young man's father. I sent a GEDcom with all the information I have but since recent enough people to be his father are not easy to find through genealogical sites, he will have some work to do.

My cousin, his brother, and their children are not possibilities for the father. The sperm bank was in California and none of them went to school or ever lived there.

What I have determined is that the 4th great probably was not fathered by a man with the surname we know. The closest other matches have been a selection of men with various surnames. One of those was advised that his ancestor was likely the result of an "undocumented paternity event!"
