I settled on John married to Alice in 1901 and 1911.
Chasing Newcastle newspapers for John Smith, John Thomas, Thomas Smith, John T Smith or John Thomas Smith with a theatre connection and assuming I'm not looking for a Burton or a Gielgud.
Closest to date is a 1905 report of John Smith, scene shifter, falling off the stage and breaking his neck. The date rules him out given the 1911 Census.
