More on the new Ancestry DNA feature

So I am working on Jennie Mae's tree.  Ancestry suggests she is related to Nancy Louisa Brock (1842-1896).

Now Jennie's tree is pretty clean to 1900 so it should be easy to spot this relationship.  Originally I thought the link would have to be through one of Nancy's kids if she descended from her.  However, all of Nancy's children were all born, lived and died in the same area in which they were born, Georgia.

By 1900 Jennie only had family in Oregon and Minnesota. There is no crossover.

Now chatting with a Brock researcher, it appears there is another way to interpret the Ancestry hint.

Nancy Louisa Brock and a child out of wedlock. His name was James Leander Brock. His father is unknown and not really included in Ancestry's database.

My new theory is perhaps Jennie's ancestors, the Ray's who lived in Kentucky, might have been related to the man that Nancy had a child with.  If we cut out all the generations in between, Jennie would be half cousins to this James Leander Brock. Since Ancestry would pick up on this genetic match, and the only person in the database which James Leander Brock was related to was his mother, it would show that Jennie was likely related to her as well.

This is an exciting new way of looking at things and may provide more satisfactory results with my Lee Miller family.
