HAREFIELD, a parish in the hundred of ELTHORNE, county of MIDDLESEX, 4 miles (N.) from Uxbridge, containing 1228 inhabitants. The living is a donative, in the jurisdiction of the Commissary of London concurrently with the Consistorial Court of the Bishop, and in the patronage of Charles Newdigate Newdigate, Esq. The church, dedicated to the Virgin Mary, contains several memorials of the ancient family of Newdigate, and a splendid monument to the memory of Alice, Countess of Derby, who, about 1637, founded and endowed almshouses for six poor widows. The Knights Hospitallers had here a preceptory, a cell to that of St. John, Clerkenwell, the chapel of which, still standing, is in the early style of English architecture. The parish is bounded on the west by the river Colne, and the Grand Junction canal passes through it.
