Would there have been a local Mill, brewery and Clay pit employers and would you happen to know what a Trammer did in the clay pits.
Mills - yes. I have a map from a later date which shows Netherton Mill and Holme Field Mill a short distance to the west; I'm not sure what the precise location would be - Holdsworth? And there would probably have been others within a mile or so.
Brewery - yes. Pigot's Directory (1834) lists Joseph Stocks & Co at Shibden Head - again very close, just on the eastern edge of Ambler Thorn.
Clay pits - are you sure it isn't coal pits, of which there are quite a few nearby? Clay mining isn't something the West Riding is particularly known for. On the other hand the map shows dozens of sandstone quarries in the area - maybe someone who knows a bit about geology might be able to say whether this makes clay pits more or less likely.
Trammers are apparently young mineworkers - see
