Thanks, Andy. Funny you should mention Crowther as my husband just this week found out one of his relatives married a Benjamin Crowther in the 1890s, whose family came from Sowerby. When I traced him back, I get his grandfather or grt grandfather (forget which), Thorp Crowther, (I know Thorp is also 'a name'), in Sowerby. I think Joseph C's dad's name was Richard, though. And can't as yet see if Thorp and Richard are related in any way. He was a Crowther from Sowerby, though and the only Yorkshireperson on my husband's entire tree!
My own family were clothiers, woollen weavers, and croppers in Halifax and Huddersfield at this time. One lot moved from Halifax to Huddersfield, somewhere between 1812 and 1819. Their names were Smith (I have a Thomas Smith, as well but presumably no relation! Mine was a 'Fancy Wool Manufacturer' at Longwood, nr Huddersfield, and a bit younger than 'the' Thomas Smith - mine was born 1799). And my weavers/cloth dressers were Listers and Crabtrees. Can't yet link them to anything Luddite related. My Thomas Smith went into partnership with one of the Hansons, to start a mill at Longwood and I noticed from the 1813 newspapers, that one of the witnesses who gave an alibi for a Longroyd Bridge Luddite was a William Hanson.
