I am interested in the Robert Adair McTyer you are related to. I am descendant of William McTyer and Elenor Ann McTyer. We have no been able to find out what her maiden name was. They had a daughter named Sara Elizabeth McTyer who married David Anthony Griffin. Another daughter named Martha I. McTyer who married Samuel Fulton from Alabama. I know that William McTyer's fathers name was also William. My William who married Sara Elizabeth was born in 1800 in NC. I am trying to connect to the Cherokee Indians. Any help would be appreciated.
