Discover the William Floyd Estate

The William Floyd Estate is the center of local and national history spanning 250 years seeing change and continuity. The Floyd family name became synonymous with the American Revolutionary war effort. As an active member of the American Revolution, William Floyd was one of four New Yorkers to sign the Declaration of Independence. He devoted himself to public service, in addition to the Floyd family business. The Floyd family grew their enterprise as affluent merchants and landowners in the town of Brookhaven, New York as early as the 17th century.  By 1718, the Floyd’s acquired 4, 400 acres, in which Nicoll Floyd built the family’s ancestral home, the Old Mastic House, and ran a prosperous Northern plantation, which was passed down to William Floyd and later generations. Over the years, the Estate became a summer home and eventually donated to the National Park Service’s Fire Island National Seashore unit in 1975.  
The Estate’s long family history is not the only aspect to make this place notable. Enslaved, indentured, and indigenous people are the thread that sewed together the Floyd’s family successes. Their skill and labor played an integral role in the operations of the Floyd’s plantation, and lucrative industries, such as whaling, that defined the family’s local history at Mastic Beach. The experiences of the enslaved, indentured, and indigenous have left a legacy on this historical landscape. The presence of the enslaved, indentured, and indigenous laborers at the Estate contradicts William Floyd’s participation in the fight for freedom and independence. Shedding light on our nation’s controversial past by interpreting well rounded stories allows us, as a people, to reconcile the past to create a more equitable future.
