I doubt it's anyone other than David Wilson Abernathy, b. 1767, wf Ruth Vance, and eldest son James Milton Abernathy. Found 1830 & 1840 in Jefferson Co, AL with 3 more sons and several daughters. David & Ruth both d. aft 1850 Federal census of Pontotoc Co, MS. Youngest son's family remained in Jefferson County AL when most of the rest of the family moved on... I also believe that in this case the nearby census presence of Charles Bradshaw, Nathan & James Abernathy is only happenstance.
