I have Jacobus Westervelt bpt. 7 Sep 1712 Hackensack, NJ m. Debora van Schyven 28 Dec 1733 Schraalenburgh, NJ with children Jan bpt. 1734 Schraalenburgh, Jacobus bpt. 1737 Tappan, NJ, Isaac bpt. 1740, and Dirckye 1742 Tappan. I am descended from Jacobus/James so know a bit about he and his family. What happened to the other three?? There are so many supposed death dates for each on Ancestry.com, but no documentation at all.
