Looking for Britton S from Virginia

I am related to John Britton (b.8 6-25-1768, d.11-1-1838) who migrated from Virginia with his brother George (b. 8 Nov 1742, d.8 July 1842) to Oglethorpe County, Georgia. He and his wife, Mary Edwards(b.23 Sept 1770, d.after 1842), ended up in Butts County, GA where they were members of Sandy Creek Primitive Baptist Church and are buried in the Church graveyard. If any one has any information about this family, please let me know.
