Frederick Philipse, first Lord of the Manor of Philipseborough and patriarch of the Philipse family, was a Dutch immigrant to North America of Bohemian heritage. A merchant, he arrived in America as early as 1653. In 1662, he married Margaret Hardenbrook de Vries, a wealthy and driven widow. Together, and variously in league with slavers, pirates, and other undesirables alongside the prominent and respectable, the couple amassed a fortune.
