Hendrick Jansen Oosteroom was my 8th great grandfather. Here is how we relate:
When Hendrick Jansen Oosteroom was born in 1630 in Netherlands, his father, Jan, was 25 and his mother, Claudina Relyea, was 24. He married Tryntje Lubbertse VanBlarcom and they had five children together. He then married Geesje Jacobs on May 23, 1666. He died in 1670 in Poughkeepsie, New York, at the age of 40.
Here is a photo of records regarding his 2nd marriage:
His name later became Hendrick Jansen Ostrom. A comment made on Family Search.org reads: “The Dutch of New Amsterdam did not use surnames until 1664 when British took control & renamed New York. The surname “Oosteroom” as entered here has seven alternate spellings as seen on records of time frame – whoever could write spelled & wrote what was heard, not what was meant to be heard”
He was also called Hendrick Van Schalwyk which used the place of his birth as his name.
In 1654, there are records of him receiving a land grant for 25 mogens of land in Kill van Kull, the site of what would later be, Bergen New Jersey. Because of problems the settlers were having there with the Native Americans, it seems that Hendrick later took a lease for unsettled land in Poughkeepsie, Dutchess County, NY. which was a part of British Colonial America. From familysearch.org “He was apparently living in New Jersey when the Indians forced all white persons living west of the Hudson to retreat to New Amsterdam, where his second child was born in 1657.”
