I do not have any information on John Clayton Stegall or his parents. Do you have any reason to believe that he ever lived in Sumter County, Alabama, or are you just checking every county in the state? Stegall is not a common surname in Alabama. Our Stegall family came over from Pontotoc County, Mississippi around the turn of the century. I have heard of other Stegalls scattered around the state, but not many. There is a family in the Birmingham area and another in the Montgomery area. Have you searched the 1910 census? I believe that the Clayton Library in Houston, Texas has an index of persons, by state, in each census up through 1920. Good luck! Joe Stegall
