I am trying to find out who is the father of William B. Clements. William B. Clements was my Great Great Grandfather. He was born in 1823 in Kentucky.. I think his father might be Hannibal who was born in 1803. Hannibal was the brother of John Marshall Clemens I, father of Mark Twain, making Hannibal Mark Twain's uncle. Hannibal may have been married in his early 20's. Later on he married Jane Hudson Jones on 09 Jan 1829. They had two or three children, not sure. Hannibal died in 1836. Hannibal and Jane Hudson had a son named John Marshall Clemens II in 1835 or so. Any help would be greatly appreciated.
