From www.genuki.org.uk: "HEANOR is a neat village and populous township, in the parish of its name, and in the same hundred as Ilkeston, about four miles N.N.W. from that town, eight and a half N.E. from Derby, and eight S. from Alfreton. This place, which was formerly a market-town, is pleasantly situate on an eminence, and the eastern boundary of the parish is watered by the Erewash river. Many of the inhabitants are employed in the neighbouring coal works, and others in the manufacture of lace.

The places of worship are, the parish church, dedicated to St. Michael, and chapels for independents and Wesleyan methodists. The living of Heanor is a discharged vicarage, in the patronage of the crown. The ruins of the ancient castle of Codnor, founded by Richard de Grey in the reign of Henry III, may here be traced over a considerable extent of ground, and some of the walls are still standing. The market market, formerly held on Wednesday, has long been discontinued; an attempt was made to revive it some few years ago, but without success.

The entire parish contained, in 1821, 4,981 inhabitants, and in 1831, 5,380, of which last number 2,672 were returned for the township.
