If you are still monitoring this, I have your information.
Cynthia, or Syntha Skelton (spelled many ways, but mostly the first way) was indeed the sisteer of Jeremiah Bobo Skelton, Senior. I show she was born about 1815,but I don't have a marriage date for her. She did marry Middleton Fain, or Finn. I come from her older brother, Noel Skelton, who lived in Hart County, which was created from parts of Franklin and Elbert. Can you tell me what your source is for the marriage date? Also, how did you findo ut where they were buried? I would like this information, and I will look up what I can find for you.
