BRIGHTWELL, a parish in the hundred of MORETON, county of BERKS, 2 miles (W. N. W.) from Wallingford, containing, with the hamlets of Mackney and Slade-End, .546 inhabitants. The living is a rectory, in the archdeaconry of Berks, and diocese of Salisbury, rated in the king's books at £44. 17. 11., and in the patronage of the Bishop of Winchester. The church, dedicated to St. Agatha, contains, among other monut ments, one to the memory of Thomas Godwyn, D.D., author of a treatise on the Jewish and Roman antiquities, who died rector of this parish in 1642. There is a meeting-house for dissenters. The parish is bounded on the north by the river Thames, and on the south by the Tadsey. Here was anciently a castle, which, in 1153, was given up by Stephen to Henry II., then Duke of Normandy, after the treaty of peace concluded between him and Matilda at Wallingford, and probably soon afterwards demolished, for its site is not even known, though conjectured to have been within the moat where the manor-farm-house now stands. Frances Riggins, in 1726, left a small annuity for the instruction of children, and for supplying the poor with bread. The Bishop of Winchester, as lord paramount, holds a court annually.
