I don't have a whole lot on this line as they are not my family, but I think that you left a generation out: The father of Christopher was John Pinkham, b. 15 sep 1707, Nantucket d. abt 1737, m. Abigail Bunker, b. 9 Nov 1712, Nantucket, d. 18 jun 1799. John's father was Jonathan, Abigail's parents were Jonathan Bunker and Elizabeth Coffin. I have other info if you need it - I'd like to share with you as I have nothing after they moved from Nantucket.
