In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Britwell Prior like this:
BRIGHTWELL-PRIOR, or Britwell-Prior, a chapelry in Newington parish, Oxford; under the Chilterns, 1¾ mile SW of Watlington, and 7½ NW by N of Wallingford-Road r. station. Post Town, Britwell-Salome under Wallingford. Real property, £866. Pop., 43. Houses, 6. The manor belonged formerly to the Welds; and Brightwell House is now the seat of H. Reeves, Esq. An ancient priory stood here; and a nunnery of St. Clare was set up for some time by French Nuns who fled from the first revolution. The living is a p. curacy, annexed to the rectory of Newington, in the diocese of Oxford. The church is Norman in the nave, and early English in the chancel; and has a decorated font.
