Margrieta Philips Leeuwenhoek
When Margrieta Philips married her step-father's son Jan Jacobs de Molijn on 1643 05/08, he was living on the Choorstraat and she was living in Amsterdam. They registered the betrothal in Delft at the Nieuwe Kerk and at the Stadhuis, but they got married in Amsterdam (Amstelveen?). Eleven-year-old Antony may have attended his sister's wedding, and she may have been living with their uncle Peter Douchy, where Antony would later live.
She and Jan de Molijn lived in on C0258 now Choorstraat 33 Molijn's house just one street up from Antony and around the corner. It was also directly across the street from where he grew up and where his father had lived with her mother, who may have lived there until her death in 1664.
Antony witnessed the baptisms of the last two children, Anthonij on June 18, 1656 and Geertruijt on January 23, 1661.
