thank you for your reply.So, we share the same great-great-great grandparents: William Mark Harper and Barbary Cox Harper.I am a descendant of their son, William C. Harper and you are a descendant of their daughter, Barbara Cox Harper.The list of children I have for WM Harper and Barbary Harper does not include Barbara Cox Harper for some reason.I have John Halbert Harper B. 1808, William C. b. 1811, Sarah b. 1814, Henry T. b. 1823, elizabeth M. b. 1830, and Robert.Where does Barbara C. fit in?What was her birthdate?And do you have any information about William Mark's parents?I do have information on Barbary cox Harper's parents and grandparents.
