In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Clayton like this:
CLAYTON, a parish in Cuckfield district, Sussex; on the London and Brighton railway, 1 mile S of Hassocks-Gate r. station, and 2 SE of Hurstperpoint. It has a post office under Hurstperpoint, and fairs on 5 July and 26 Sept. Acres, 2, 402. Real property, £3, 456. Pop., 863. Houses, 164. The property is divided among a few. ...
Clayton Priory is the seat of the Elwood family. A tunnel of the railway through the South Downs, 1½ mile long, commences a short distance south of the church, and was formed at a cost of upwards of £90, 000. The living is a rectory, united with the p. curacy of Keymer, in the diocese of Chichester. Value, not reported. Patron, Brazenose College, Oxford. The old church is early English, with a round chancel-arch, of quasi-Saxon character. A new church was built in 1863, at St. John's Common, at a cost of £6, 000; is in the decorated English style, and cruciform; and the charge of it is a separate vicarage, in the patronage of the rector.
