My husband and I recently did AncestryDNA. He came back with a DNA match (shared with his mother) that simply says "close relative". He has no idea who this person is, and his mother claims she's never heard of him.
The person in question does not have a tree, and it appears they haven't logged on to Ancestry for more than a year, so I don't hold out hope for an answer to messages.
That said, any ideas on possible relationship?
I am new to DNA testing and interpretation of its results.
