Winsor is first recorded as Windesore in 1167, and Windlesore in 1222. The name apparently derives from "windels-ora" meaning "winch on a bank". In the 13th century there was an estate at Winsor and at nearby Cadnam which belonged to the nuns of Amesbury, who in 1286 obtained a grant of free warren in both estates.
