A Double Wedding in 1920 Walkley Sheffield

A great photo showing a family wedding in Woodview Road Walkley Sheffield that was taken in 1920.

I could not find any trace of "Bullors" in the 1911 UK census but enter the name "Bullers" and there are quite a few entries inj the Crookes/ Walkley area. But what I can't find are any entries for the marriages in the BMD registers. If her maiden name was Bullors/Bullers then you would expect her father and uncle to have that name but so far I have not been able to trace them
