Yes - I have got their marriage certificate in 1904, stating that they were married at the Ebenzer Chapel Marsden Moor Staveley, Chesterfield. Haven't been able to find anything about this chapel - i.e.. parish records, it was apparently a Primitive Methodist marriage.
Both William and Beatrice were living in Birmingham prior to their marriage - not sure when they moved up to Derbyshire.
I am about to order Beatrice's possible death certificate, in Ecclesall Bierlow in 1919, - don't know if she did move there, also the possible birth certificates of the two children mentioned in 1911 census hoping I may get some more info. from them.
Many thanks for your help tho'.
