Pigot and Co.'s Royal National and Commercial Directory of August 1841:
Golcar is a populous township in the parish of Huddersfield, extending from about two to five miles west from that town. The manufacture of coarse woollen cloths, chiefly for the Huddersfield market, is carried on here to a great extent; and finer cloths are also made, with which some of the inhabitants travel through different parts of the country. In the production of these articles a very considerable power from water and steam is employed — there being in motion, in the two townships of Golcar and Longwood, twelve water wheels, of the united power of one hundred and seventy horses, and three steam engines, equal to the exertion of fifty-seven horses. In Golcar a church was erected, in 1829, from the fund placed at the disposal of the commissioners appointed by parliament for the erection of additional churches: it is dedicated to St. John; the living is in the presentation of the vicar of Huddersfield. There are two free schools, erected by subscription in 1816; and one upon the national plan, opened in 1831. The township of Golcar contained, by the returns for 1831, 3,143 inhabitants.
A Topographical Dictionary of England (1848) edited by Samuel Lewis:
GOLCAR, a chapelry, in the parish and union of Huddersfield, Upper division of the wapentake of Agbrigg, W. riding of York, 3¼ miles (W. by S.) from Huddersfield; containing 3598 inhabitants. The township comprises by computation 1560 acres, of which the surface is boldly undulated, rising in steep acclivities from the banks of the river Colne: here are several quarries of excellent stone. The manufacture of coarse woollen-cloths and padding has long been established, and that of articles of the finest texture has since been introduced; the machinery of the numerous mills is propelled by 12 water-wheels and 12 steam-engines. The Huddersfield and Manchester canal skirts the township, which contains various hamlets scattered on the sides and summit of Golcar Hill. Commodious baths have been erected at a mineral spring on the course of the Colne, the waters having been found useful in rheumatism and other disorders. The chapel, now a district church, dedicated to St. John, was erected in 1829, at an expense of £2865, defrayed by the Parliamentary Commissioners, with the exception of £500 raised by subscription; it is a handsome structure in the later English style, with a tower surmounted by a spire, and contains 950 sittings, of which 430 are free. The living is a perpetual curacy, in the patronage of the Vicar of Huddersfield; net income, £150. There are places of worship for Baptists and Wesleyans. Upon the high ground at the western extremity of the township was formerly a rocking-stone, so celebrated as to have been marked in old maps; and it is said there were other Druidical remains.
