Col I found several more in another file: COALMASTER: Owner and operator of a coal mine COAL TRIMMER: A person who stabilised coal-carrying barges/ships COLLIER: Coal miner, at the coal face HEWER: Miner underground working at the coal face OVERMAN: Supervisor in colliery checking mine and coal quality PITHEADMAN: Over-ground worker at a coal mine (pit) PIT BRUSHER: Coal miner who repaired mine passage roofs and sides PIT ROADMAN: Mine worker preparing and repairing underground passageways PONY DRIVER: Leading pony underground pulling coal hutches There may be others I missed when I scanned through. I had no idea it was so complex. It's a bit difficult splitting hairs with some! Kindest regards Julie
