In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Monken Hadley like this:
HADLEY, or MONKEN HADLEY, a village and a parish in Barnet district, Middlesex. The village stands on high ground, near Enfield chase, the Great Northern railway, and the boundary with Herts, 1 mile NNE of Barnet; is a pretty rural place; and has a post office under Barnet, London N. The parish includes also part of the High street of Barnet. Acres, 2, 530. Real property, £5, 194; of which £100 are in gas works. Pop. 1, 053. Houses, 200. The manor was given, by Geoffrey de Mandeville, to Walden abbey; and, by Henry VIII., to Lord Audley. ...
Hadley House is a chief residence. The high land around the village once formed a part of Enfield chase. The battle between the Yorkists and the Lancastrians in 1471, was fought partly within the parish; and is commemorated by an obelisk, erected in 1740. The living is a donative in the diocese of London. Value, £199.* Patron, the Rev. F.Cass. The church is ancient and cruciform; has a western square tower, built of flint with stone coins, and bearing the date 1494; was thoroughly restored in 1848; and contains several interesting monuments. Au iron beacon is on the top of the tower; supposed to have been used for a signal light to moving monks or armies; and was last illuminated on the occasion of the Prince of Wales' marriage. There are a Weslcyan chapel, national and infant schools, two suites of alms houses with £120, and other charities with £12. Staunford, the lawyer, and Atkyns, the historian of Gloucestershire, were natives.
