If either of you still have that information handy, I would like to see it. I have John & Jorden (Jordan) Chaffin supposedly coming from overseas in the early 1710's. There is no history of a Jorden or Jordan Chaffin coming on a ship at that time (that I can find).
Maybe the clue is with the Chipman last name? Please let me know if this is the time frame you are looking at - being the early to late 1700's.
