Richard Floyd, first appeared in American records in the late 1660s as a leading landowner on the North Shore of Long Island, first in Huntington, then in Setauket.
A half-century later, in 1718, his son Richard Floyd II (1665-1738), bought over 4,400 acres of property from William "Tangier" Smith of the Manor of Saint George. The property stretched six miles north from Moriches Bay and approximately one mile west from the Mastic or Forge River. It included use rights for the Great South Beach on what is now Fire Island. Richard Floyd II gave this property to his youngest son, Nicoll Floyd.
The first Floyd to live on the estate, Nicoll Floyd built the first portion of the "Old Mastic House" in 1724, constructing a two-story, six-room shingled wood frame house. He developed the land into a prosperous plantation, using both slave and free laborers to raise grain, flax, sheep, and cattle. Nicoll Floyd expanded the home as his wealth and his family grew. Nicoll Floyd's oldest son, William Floyd inherited the property in 1755 at the age of 20.
General William Flloyd was born in Mastic Neck on December 17, 1734. He was an officer of the Suffolk County Militia for years, and in 1775, he was a Colonel in the First Suffolk Regiment. At the end of the Revolutionary War, he received a commission as a Major General. He served a shirt term in the Provincial Assembly of New York and was delegated to the Fist Continental Congress at Philadelphia. He became one of the signer of the Declaration of Indepedence, He was a State Senator from 1777-1783 and again from 1784-1788.
He retired, leaving his home in Mastic Neck to his children. The house was sheltered on all sides by dense wood growth. The oldest part was built around 1724. Additions were made at an early date, so the house is virtually the same as when the General lived there.
The Estate was authorized as an addition to Fire Island National Seashore in 1965. The 25-room "Old Mastic House," the twelve outbuildings, the family cemetery and the 613 acres of forest, fields, marsh and trails all graphically illuminate the layers of history.
