Did you contact the people responsible for establishing and maintaining the findagrave memorial? Perhaps they are privy to death info? If he died, 1910, in Texas and was returned to Alabama there probably will not be an official record? Texas mandated vital records effective 1903 but compliance lagged for several decades thereafter. Via daily research, I'm aware of a few people who died as late as 1950s but do not have certificates. Also, there are partial pedigrees on him that are viewable on https://familysearch.org/
Simply search Seabolt deaths in 1910 Alabama. At the bottom of the page, access user submitted family tree info. One final question? Who was the daughter identified as Elmira M. in 1880 Cherokee, GA? She's missing from 1870 Lumpkin, GA. The "old man" married Jane 30 Aug 1868 therefore she was mother of Fanny, Ellen, Sarah, and Charlies? Oops, that's a second question.(lol) I'd appreciate an invite to your tree eventhough I'm not related?
