My GGGrandfather was James Hart of Hartsville, Tennessee. From what I know the only hart's in Hartsville at that time were the families of James Hart and his brother Matthew Hart.I found the following in some old Hart Papers. "Elizabeth C.Hart,a niece of James Hart, married Esquire D.M. Potts, Father of R.M.Potts, 23 November 1841."I don't know when this was written or by whom. If this is your family I would love to learn more about what happened to them.
