Founded by prospector M. Monaghan who arrived from Minnesota in 1888. At an early date took up 160 acres of land here, where CPR eventually built a siding. (Nelson Daily News, 25 December 1932). "In 1905, [John Bell] and A.G. Lambert became partners, an association that lasted six years, building and operating a mill at Lebahdo. After a couple of years they moved the location to Taghum." (John Bell's obituary, Nelson Daily News, 5 December 1932). "A.G. Lambert ... said that although only a few men were at present working at his mill at Taghum, a boiler was being constructed ..." (Nelson Daily News 31 March 1909).
