Trying to confirm date of death of Martha Tennessee (Warren) Potts, wife of William Burton Potts, daughter of Thomas M. Warren. According to one source, Martha died on Mar. 22, 1851, and is buried at Concord Cemetery in Choctaw County, Mississippi. Census records show Martha's youngest child, as being born about 1854. Thomas M. Warren's will states that his daughter, Martha T. Potts, as being deceased prior to 1857, the date of T. M. Warren's will. Any help in obtaining the correct date of death and place of burial of Martha Tennessee (Warren) Potts would be gratefully appreciated. Thanks.
