Sullivan Leigh deeded 500 acres to his son, Richard Stanford Leigh, on "the waters of Newhope Creek" in 1834. Shortly before, Stanford had married Nancy Ann Carlton, a granddaughter of John Daniel, who with others granted land for the University of North Carolina at Chapel Hill. Stanford and Nancy Leigh had 15 children, and family documents show them to have been cultured, educated people closely associated with old Chapel Hill. Nancy Leigh died as the Civil War broke out, and Stanford married Lethy Hawkins Hudgins in 1864. This union that yielded five more children. Richard Stanford Leigh died in 1898, leaving nineteen surviving children by his two wives. Many of them are buried in this cemetery.
