I have copy of the certificate:
20 Dec 1900 Kirk Braddan Parish Church. John William Callow 25 (Fireman) living at 9 Murray's Road, father William Callow - Labourer. Violet Dumphey 22 living at Cronkbourne Village. Father Nicholas Dumphey - Flax Dresser.

I also have JWC's second marriage to Violet's sister Minnie. As you are aware they had relocated with most of the family to Stockport sometime between 1915 and 1921. They were both living at 56 Grimshaw Street, Stockport at the time. Nicholas had died by then as had William Callow. They were married at the Register Office, Stockport 11/11/1929. JWC died just over a year later (30/1/1931) Minnie 1/12/1963

For your further info, Nicholas, Minnie (Dumphey), John William, Lily (the Dumphey's third daughter) and Gladys Callow (JWC's sister) are all buried in the same grave in Stockport Borough Cemetary - no gravestone.
