Sunninghill Park was originally part of Windsor Forest until 1630, when King Charles I granted it to Thomas Carey. Around 1633, it was purchased by Sir Thomas Draper and sold in 1769 by his great grandson, Thomas Draper Baber, to Jeremiah Crutchley, whose family owned it until it was sold in 1936 by Percy Edward Crutchley (whose maternal grandparents were the owners of Eldon House in London, Ontario).Robin and Terry Harris, eds. The Eldon House Diaries: Five Women's views of the 19th century Toronto: Champlain Society, 1994, page 343. The first significant house was built on the estate in the late Georgian period in the early 19th century, being a stucco building of two stories with later additions.
