Charles,Abraham is buried in Poplar Springs cemetery in Coosa Co. Al. I don't know where Mary and Isaiah are buried either. I don't even know for sure where they lived. I know some Grogans lived in the coppermine area in clay co. The old home place of Newt (who married Menecia Moore)is in Talladega co, which if you walked across the mountains you would come out in clay co. I think they may have followed Horse creek. Are you from this line?
