Title: Can the Ancestry computer pick up shared 8th great grandparents for DNA matches?
Post by: Althea7 on Saturday 25 July 20 00:48 BST (UK)
If you go way back past the fifth great grandparents, and then trace the descendants down, will the Ancestry computer be able to use any of that?  ThruLines only goes up to fifth great grandparents, so if you have a DNA match to somebody you share 8th great grandparents with, would that show up on ThruLines or on anything Ancestry does?

Would the Ancestry computer be able to link the fact that you share say 15cM of DNA with somebody and that you share 8th great grandparents with them too?

Would Ancestry even pick up shared 8th great grandparents from two trees?

I suppose that is beyond the scope of ThruLines?  So if the shared 8th great grandparents were only on one tree, it wouldn't make use of all the other trees to piece the connection together?
