Well then, it does seem like that strong contender is truly a match.
Also, for what it's worth, that particular Miles Abernathy appears on the 1850 and 1860 census in the household of Philip and Mary/Polly (Arndt) Abernathy, who were married on 26 May 1836 in Lincoln County NC, bondsman Miles C. Abernathy, Elisha Saunders, JP. The Catawba County Cemeteries book (Vol II, p. 68) lists the tombstone inscription of Philip's father, Seth, who died 4 May 1822 and is buried in Mt Ruhama Baptist Ch, Catawba Co, NC along with most, if not all, of his children.
That tombstone inscription cites wife Polly Cline and children: Miles, Nathan, Philip, Philecta, Polly, Gertrude, Usley. Most on-line databases show Seth as a child of Miles Abernathy and Ursula Bradshaw, but the date of Seth's birth (Nov 1779) pre-dates the marriage (6 Oct 1781, Lincoln Co, NC) between Seth Abernathy and Polly Cline. Seth's marriage bondman was Henry Finger (Ger: Heinrich Finger), and Seth signed with an X, indicating that he wasn't then able to write his own name.
To date, I don't know of anyone who offers an alternate set of parents for Seth from the typically cited Miles and Ursula (Bradshaw) Abernathy. I personally believe there is still more work needed to sort out some of these very very early (and very numerous) Abernathys in the Tryon-Lincoln County area.
One has to keep in mind that when one is dealing with individuals in that early of a time frame in our nation's history, especially if there is evidence they couldn't read/write, that the possibility for errors increases. These people were, for the most part, simply too busy just taming the wilderness, rearing children, and keeping alive against hostile Native Americans to be all that concerned with leaving records for future genealogists.
