Ridge is a hamlet and census-designated place (CDP) in the town of Brookhaven, Suffolk County, New York, United States. The population was 13,336 at the 2010 census.[2]
See main article: Manor St. George. In 1693, William "Tangier" Smith, who owned a homestead in Setauket, was allowed to purchase a large tract of land on the South Shore of Long Island in recognition of his being mayor of Tangier in Africa. The land, called Manor St. George, stretched from the Carmans River (then called the Connecticut River) in the west to the edge of the town of Southampton in the east, with a northern border around present-day New York State Route 25, as much as 81000acres of land. He made his manor seat on the South Shore in present-day Mastic, and the northern part, now the south side of Ridge, was called "The Swamp" or "Longswamp". A house wasn't built at Longswamp until after the American Revolution. In 1817, William Sydney Smith inhabited the house and changed the name to Longwood.
In 1955, what then remained of William Smith's original manor was primarily located in Ridge and was surrounded by the world growing up around it, in the form of the Brookhaven National Laboratory and the surrounding areas becoming increasingly populated. Longwood's fell into the hands of Elbert Clayton Smith, who immediately moved his family from California to live there. He seems to have been very generous to his new community; his donations included to the school board for the construction of Longwood High School and to Middle Island Presbyterian Church. In 1967, Elbert Smith died, and the Longwood Estate was carved into housing developments and nearly destroyed until enough noise was made about preservation to have the house and of land given to the Town of Brookhaven in 1974. The Smith Estate was added to the National Register of Historic Places in 1981.
In 1738, northern Ridge was settled by widower Samuel Randall of North Stonington, Connecticut; his only son Stephen Randall and his descendants farmed a 4000acres plot of ground that Samuel had always referred to as "the Ridge" based on the geographical terrain. First called "Randallville", Ridge was the name selected by its residents for postal delivery. The Randall burial plot near the William Floyd Parkway includes the grave of Lt. Stephen Randall (1736–1818), patriot of the American Revolution and a Suffolk County Militia veteran of the Battle of Long Island. Graves of Randall's wife Elizabeth Swezey (1747–1834) and several descendants are also within the plot.
Ridge is located at the northwestern end of the Long Island Central Pine Barrens and is referred to by a sign in the center of the hamlet as the "Gateway to the Pine Barrens".[3]
