Hi Jan -- For what it's worth, there was a Miles Linford Abernathy in Hanging Dog, Cherokee Co., NC. According to Brian Abernathy's database, he married Tabitha Palmer, whose mother was Vina (short for Vinara?) Lundsford Palmer.I think this Miles would be about the same age as the one you mention, but the children don't seem to match.
Since a lot of the Abernathys were back and forth between Bartow, GA and Cherokee, NC, you might want to check these connections.
This Miles Linford was s/o Michael and Isabella West Abernathy.
