Walter was my Great Grandfather too. My father was John Walter France who ran James France & Co until his death in 1971. Walter's eldest son Harold (1882-1940) was my fathers father.
Edwin was the 3rd child of Hiram (born 1796) who was the son of James France (1771-1840) who first founded James France and Co, believed to be in 1790. Hiram was married to Elizabeth Aukland and Edwin to Harriet Heminway of Earlsheaton.
James was born in Halifax and the 1790 census listed him as a "carpet manufacturer late of Halifax". He was descended from a family whose name was changed from Stuart after the uprising of Bonnie Prince Charlie had been crushed at Culloden. Our family tale is that our ancestors fled to France after Culloden, returning with the new surname of "France" for safety rather than Stuart.
I inherited the family genealogy file after my mothers death. There is lots in it and it is a big job to sort through everything. I also have some files relating to James France & Co but I think these only deal with business matters relating to the demise of the business. Asda in Dewsbury now sits on the site of the old mill.
How are you related to Walter?
