I do not know anything about Joseph Smith Morgan's ancestors, but, if the Joseph Smith Morgan you refer to was b. December 6, 1804, died July 29, 1858 and is buried in the Morgan Cemetery in DeSoto County, Mississippi, I have little information on his wife, Clarissa Agnes Stone, b. December 23, 1825 in South Carolina. If this is your Joseph Smith Morgan, I will email you what I have on Clarissa Agnes Stone. I do know that there were two Morgan lines in Marshall County, Bethlehem/Potts Camp area. As far as I know, they are not related. Sylvia
