Further to my earlier post re Thomas Curwen in the 1871 census there is, as transcribed, a Thomas Cerwen ( again the original could easily be read as Curwen) living at Moor Roe, Egremont, Whitehaven. He is 23, unmarried, an iron stone miner, a lodger with the Moffat family. His place of birth is given as Ulverston, Lancashire ( like Barrow in the Furness Peninsula). Presumably Moor Roe is the Moor Row quoted in above posts.
This is RG10 Piece 5263 Folio 20 Page 34.
