For Joann, JACOB PIATT (s/o of Rene Piatt and Elizabeth Sheffield) married MARY HULL. They had at least 9 children with the eldest being DINAH PIATT, b Feb 1703/04, Piscataway NJ; dd 1789; m c1722, Piscataway NJ, to JONATHAN MARTIN as his third wife. It would seem that their son JACOB MARTIN would be the one you have marrying ELIZABETH DUNHAM. And I have no doubt that there was more than one Elizabeth Dunham as Dunhams were numerous in New Jersey. -- Laverne Ingram Piatt Ontario, OH
