The DAR lists patriot #A055804, James Hill, b. 1758, d. 1831 Amherst County, VA, with a wife Anne and children James, Nancy, Lucy (married to William Garvin), Mary, Parmelia, and Tabitha, so it looks like he’s the correct man. He’s in the DAR database for patriotic service, not military service. There was a different James Hill who actually served in the military.
James has a duplicate profile with more into that seems to be more accurate - Hill-8118. I proposed a merge
