Meacham S of Meriweather CO GA

Looking for anyone who can help with Meacham Family history. My husband is the great grandson of Sophia Meacham who married Littleton McWilliams. Sophia is the daughter of Enos J. Meacham (Edward) and Malissa May. Enos is the 5th child of James Henry Meacham of North Carolina and Jeriah Yarborough. There has been much talk in the Livingston family for years that Sophia was a Native Indian. Help can't find that info. Anyone know?? here is our family tree so far i need help filling in some gaps

Charles R. Livingston son of Ava Virgina McWilliams (1898-1955), Daughter of Sophia J or C Meacham (1864-1929), Daughter of Enos J Meacham(1835-1905), Son of James Henry Meacham(1776-1845), Son of John Meacham (1746-1811)
