I show Moyike Langstraat (1730-26 Jun 1815) married with Reinier van Sicklen III (17 Nov 1723-12 Dec 1803, both of New Jersey.He was of Readington, Hunterdon County and she was from Shrewsbury, Monmouth County, New Jersey.
They were married on 29 Apr 1746 in Monmouth County, New Jersey, probably in Shrewsbury.From this union was produced at least one child, George Warne Probasco, born about 1747.
I also show that Katrina van Sicklen was born 15 Jun 1758 in Hunterdon County and Jacob Probasco was born circa 1754 in Hunterdon County; they married about 1776. From this union was produced at least one child, George Warne Probasco, born about 1777.
I hope that this may help.
Richard McCool is a denizen of these boards, and was kind enough to provide the aforementioned data.
