I consider Geesje Jans to be the matriarch of the Ostrander family. Her first husband was Pieter Carstenzen. He died at sea and she then married Arent Teunis Pier(1637). The children of Geesje and Pieter used the surname "Ostrander" in early 18th century.
The children of Pieter Carstenzen by his first marriage are of interest to me. Did they all live their lives in Holland? Did any of their descendants find their way to North America ? Did the line of descendants of Pieter Carstenzen extend to 20th century?
