Yes, My "Sarah" Mitchell's parents were Jacob Mitchell and Susanna Pope.I'd say at a quick look that everything matches up except that my "Sarah" is your "Mary". I knew how the kids came to be separated from the parents, but didn't know about them being raised by an uncle. I'll have to add that to my family tree program.I've had a terrible time trying to figure out how to get the program to not confuse the double Kingman names.
I have the generation of John Kingman and Elizabeth Edson, Jacob Mitchell and Susanna Pope, and a Thomas Kingman (no info on wife, but not to be confused with his son Thomas Kingman who was married to a Mercy Randall), John Randall and Mercy Aldrich, then one generation before all of them, and then nothing.
My line comes from John Kingman and Sarah Kingman's son Adam Kingman, who was married to a Ruth White, and then their son Isaiah Kingman.Isaiah married Lucy Daniels, their daughter Saphronia Martha Kingman married an Elisha H. Brewster.End of my Kingman line.
