Two Abernathy - First,I am searching for the children of SARAH ABERNATHY that married Robert McCurdy Bankhead marriage was anywhere 1820-1840. He was born in SC but believed to have moved to TN. Also DR. SAMUEL ABERNATHY who married Janes McCurdy Bankhead in 1841 lived in Rutherford, TN possibly. These were possibly siblings that married siblings? Thanks for any help!
