I'm looking for any information on the parents of my great-grandparents Joe Roberts and wife Martha Ponder. Joe (and I assume Martha as well) is buried in San Augustine county...not sure which cemetery. Joe's father's name was "Doc" Roberts. I'm not sure if this was a nickname or not. Doc served in the Civil War and was wounded, but I'm not sure from which state he originally came...it wasn't Texas. Joe and Martha had 10 children, including my grandfather, John Thad Roberts, born in 1894. Any help would be greatly appreciated.
