CAVERSFIELD, a parish partly in the hundred of PLOUGHLEY, county of OXFORD, but chiefly in the hundred and county of BUCKINGHAM, 2 miles (N.) from Bicester, containing, with a portion of the township of Bicester-Market-End, 208 inhabitants. The living is a discharged vicarage, in the archdeaconry of Buckingham, and diocese of Lincoln, rated in the king's books at £6, endowed with £8 per annum private benefaction, and £400 royal bounty, and in the patronage of the Trustees of the late Joseph Bullock, Esq. The church is dedicated to St. Lawrence. Some suppose this to have been the place where Carausius, the Roman commander, assumed the purple in 287, and where he was afterwards slain by Caius Alectus, one of the thirty tyrants: on Bayard's Green, about a mile from the church, are faint traces of Carausius' camp.
