Looking for Hilton Helton of Georgia

My mother was a Hilton from Randolph County Georgia. In my search I have found that my ggggrandfather John C was spelled HELTON. I would love to find out who his parents were. John dob 11 Mar 1818 dod 7 dec 1891. Married Susan E Thompson on 2 Nov 1843 and had 15 children.
