The Floyd family bought the property in 1718 and lived in their beloved Old Mastic House until 1976, when they turned it over to the National Park Service to coincide with the Bicentennial of the United States.  William Floyd, one of many generations born in the house signed the Declaration of Independence for New York State in 1776.  He was the only Signer from Suffolk County and the Estate bears his name.  All total, eight generations were raised in the house and the main theme is the continuous long occupancy of the family and the changes they brought about the house, land and themselves.  The house is a Cultural Preservation and it shows the continuum of time.  Three centuries of architecture, furniture styles and land use patterns are all shown and discussed on the hour long tour.  The 25 room fully furnished house was left intact by the family so all furnishings are original to the house.
