Islip Manor was named after the Ruislip family, who owned the estate in the fourteenth and fifteenth centuries. It was part of Northolt Manor until about 1690, when it was sold to Charles Hawtrey. It was farmland until the end of the nineteenth century, and in 1880 it was producing 100 tons of hay a year. In 1928 it was sold to Ealing Council, and now forms part of the Metropolitan Green Belt.[3][4]
