Hi Jen, I can offer the following taken from a [poor] copy of a trade directory called Mcdonald's Directory of Lanarkshire 1898-9: [heading] FIRE-BRICK AND FIRE-CLAY GOODS MANUFACTURERS [listing] - Calder Fire-clay Co., Calder Brick works - Garnkirk Fire-clay Co., Garnkirk - Gartverrie Fire-clay Co., Glenboig. George A. Bishop, manager - Glenboig Union Fire-clay Co., Ltd., Glenboig, near Coatbridge; and Cumbernauld; Glasgow office, 4 West Regent st. - Heathfield & Cardowan Fire-clay Co., Heathfield, Garnkirk - Hurll, Peter, & Mark, Garliston and Garnqueen Fire-clay works, Glenboig. Glasgow office, 144West Regent st.; maker of highest quality fire-bricks, gas retorts, and furnace blocks - M'Laws, Geo., & Co., Greenfoot, Glenboig Hope this helps. As a footnote let me quote from "Placenames of the Monklands" by Peter Drummond ISBN 0 946120 20 X, published by Monklands Library Services Department, 1987: GLENBOIG comes from glen - which as all Scots know is a valley - and 'boig', meaning soft or moist: it is indeed a moist or boggy valley, as the nearby farm of Inchneuk (formerly Inchnock, 'the hill on the island') suggests, while the pit at BEDLAY ('bad liath', the grey spot) near here was notorius to its miners as a wet pit.
