In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Bolton like this:
BOLTON, a small town, two townships, and a parish in Wigton district, Cumberland. The town stands on the river Ellen, 6½ miles SSW of Wigton; consists of two parts, High and Low; and has a dingy appearance. A branch railway to it, from the Maryport and Carlisle line, was opened on 26th December, 1866. The townships are High Bolton and Low Bolton or Bolton-wood and Quarry-hill. Acres of H. B., 3,875. Pop., 330. Houses, 62. Acres of L. B., 4,570. Pop., 718. Houses, 149. The parish consists of the two townships; and its Post Town is Ireby under Wigton. ...
Real property, £8,124; of which £740 are in mines. Pop., 1,048. Houses, 211. The property is much subdivided. Coal, limestone, and copper ore are worked. A copper battle-axe was found in a bog. The living is a rectory in the diocese of Carlisle. Value, £512.* Patron, the Earl of Lonsdale. The church is ancient, in tolerable condition; and was alleged by old superstition to have been built by witchcraft.
