In 1642, Anne Hutchinson and her family moved from Rhode Island to Split Rock, along the Hutchinson River in what is now Pelham Bay Park. Although the family was English, the land was part of New Netherland under Dutch authority. The exact location of the Hutchinson house is unknown, with one scholar saying that the house was in the modern-day park on the east side of the Hutchinson River, and another saying that the house was on the west side of the river in now Baychester. The Siwanoy destroyed the Hutchinson settlement and killed the family in August 1643, in reprisal for the unrelated massacres carried out under Willem Kieft's direction of the Dutch West India Company's New Amsterdam colony.
