The Jacob J. Blauvelt house and its four remaining acres of land had been in the Blauvelt family since the time it was built, in 1832, up until when it was acquired by the Historical Society of Rockland County in 1970. The Blauvelt family first arrived in America in 1638, and first arrived in Rockland County in 1683. Their genealogy today contains more than 26,000 names.
