Nancy is my 3rd ggm. There is a post on her profile that I just answered. Richard Witt was assistant Indian Agent to Wm L Lovely. Lovely's wife was the widow Persis Brown Goodrich. Richard and Sarah named children after them, and Persis left those two 1/3 each of her estate.
Nancy was born in Indian Territory in 1814, evidently during Richard tenure.
My DNA does not show any NA, Asian or other New World markers.
I have some great work sent to me from a researcher named Sharon. It was Sharon's work that I originally saw when my Mother sent me to find Nancy's maiden name. At the time it was the only gedcom at Rootsweb who had a maiden name attached. I followed her research. Of course I had to tell my mother that Nancy told me.
Nancy's daughter's Sarah Jane and Rhoda married Morton Brothers.
