I have him in my database as a son of Robert Abernathy and Rosy Huskins, who married in Lincoln County NC on 17 Nov 1817 [src: Bynum's "Marriage Bonds of Tryon and Lincoln Counties, North Carolina", p.10]
Most online databases give birth and death dates for Rosy that I believe belong instead to Martha Elizabeth Jennings Asbury Abernathy, who married a Robert Abernathy on 14 Oct 14 Oct 1808, and was daughter of the Reverand Daniel Asbury.
Most online databases also claim that the Robert Rosy married was as son of Robert Abernathy and Abigail Harwell. I belive this is incorrect and that it was Martha Elizabeth Jennings Asbury who married the son of Robert and Abigail.
I know of not one single scrap of documentation or public records from the early 1800's that show Rosy's given name as Elizabeth, which is one reason I believe the dates for Martha Elizabeth Jennings Asbury are incorrectly assigned to Rosy.
I have, therefore, only approx b/dates for Robert (abt 1798) and Rosy (abt 1800), no death date/location, nor parents I can vouch for.
