Hi Keiran
That is my no 1 guess as to his (Jane Elizabeth's husband) death. Not got the cert as yet, but I have checked 1900-1930 death index at FRC and he is the only real possibility. (It would also sort of explain why my grandmother b. 1907 never mentioned him).
I can't believe that with such an uncommon name I haven't been able to find them in 1901, I really need at least one census or something on Jane (nee BRYANT), in order to determine likely possibles for her birth etc
