In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Long Crendon like this:
CRENDON (Long), a parish in the district of Thame and county of Buckingham; on the river Thame, adjacent to the boundary with Oxfordshire, 2¼ miles N of Thame r. station. It has a post office under Thame. Acres, 3, 120. Real property, £5, 892. Pop., 1, 570. Houses, 356. The property is much subdivided. Nutley Abbey here was founded, in 1162, by William Gifford, Earl of Buckingham; and the remains of it are now included in a picturesque farm-house. An ancient cemetery was discovered in 1824, near the supposed site of the castle of the Giffords; and yielded some curious relics of Roman pottery and sepulture. ...
A kistvaen, with urns, was found in 1849. A royalist force, under Col. Blagge, was beaten here, in 1644, by the parliamentarians. Some of the inhabitants are needle-makers. The living*is a vicarage in the diocese of Oxford. Value, £134. Patron, Lord Churchill. The church is early English and cruciform; has a bell from Nutley Abbey; and contains a font resting upon lions, and a monument of Sir John Dormer of 1605. There are Baptist and Wesleyan chapels, and charities £44.
