I'm doing research on an allied family of the Bouldins of Charlotte (Morton) and can tell you that they were a large slaveholding family. The 1764 tax list for Lunenburg lists them in Cornwall Parish with 1703 acres and 11 tithes. Thomas Sr was the first Sheriff of Charlotte County when it was organized and earlier was the first Sheriff of Lunenburg. He died in Charlotte and a will was proved in 1783 which I don't have. I currently have the 'free blacks' of Charlotte checked out from the Va. St. Library film service and the free blacks of Charlotte are only listed by their Christian names so its not much use genealogically speaking.
