In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Hardham like this:
HARDHAM, a parish in Thakeham district, Sussex; on Stane street, the river Arun, and the Crawley and Arundel railway, 1 mile SSW of Pulborough. Post town, Pulborough, under Petworth. Acres, 680. Real property, £1, 359. Pop., 87. Houses, 14. The property is all in one estate. A priory of Black canons was founded here, in the time of Henry II., by Sir William Dawtry; and some arches and mouldings of it, in transition Norman, still exist. A Roman entrenchment, about 400 feet square, on Stane street, is opposite the priory. The living is a rectory in the diocese of Chichester. Value, £66. Patron, the Bishop of Chichester. The church is early English, and bad. A yew, 23 feet in girth, is in the churchyard.
