The land on which Cedar Knoll now stands was acquired in 1654 by a prominent aristocrat and his wife, a princess of the Piscataway tribe, for their one-year old son, Giles Brent, Jr. and named Piscataway Neck. The son, who was most famous for his involvement in Bacon’s Rebellion which ended in the burning of Jamestown, eventually moved to England where he died, passing the land on to relatives. In 1760, it was purchased by George Washington, becoming River Farm, the northernmost of the five farms that made up Washington’s 18th century estate.
