Good luck with that search! Parents not identified on his or brother's death certificate. Mom apparently died prior to 1910 with no traceability of her maiden name? Marvin Ellis Gresham's certificate indicates birth in Myrtle, Union County, MS. Searching for possible marriages there, 1880-1890, results in A. B. Gresham to L. A. Wiley on 23 Oct 1880. 1880 Union, MS census has a "misinterpreted" 23-year old male Gresham in the household of Emeline Wiley. Her daughter Laura A. may have been mother of your grandfather but there is no unimpeachable proof!
