Hi Mike or anyone, I have been searching for Manchester's glassworks on maps and have found some good stuff thanks to Mike and others here. Now I want to see the site which J.J.&T. Derbyshire (flint glass manufacturers) used in the 1870s in Trentham Street. I have the Godfrey map for Hulme 1894 which shows the possible site of the glassworks, as "Cornbrook Brewery"? But by 1893 Derbyshire's had closed and I am not surprised that the glassworks is not showing. Does anyone have a map which does show "Derbyshire" glassworks in Trentham Street? It might be named something like "Bridgewater Flint Glass Works". It should appear in the 1870s, perhaps in the 1880s. Trentham Street is on the north side of Chester Road, actually on Ellesmere Street where it joins Chester Road. Mike, I think you mentioned it to me in one email but I couldn't see it on the corresponding map, so perhaps it was just a little off the portion you sent me? Thanks so much. Sally in Yorkshire
