Hi Tom Wagner, Which Jurriaan Dingman married Nancy Halverstadt. I have one Jurriaan who was baptized in the Kinderhook Reformed Church on 29 Dec 1765. He was the illegitmate son of Rachel Dingman. The Van Valkenburg website has her married to a different Jurriaan Dingman. He was the son of Andries Dingman and Lea Van Valkenburg. Richard
