Have to work on George who is the only known quantity, otherwise you are taking guesses and clutching at a Walter who perhaps has nothing to do with the family - isn't Devizes in Wiltshire?
This would appear to be the correct 1901 census and gives us an idea of his date and place of birth.

You need to keep in mind that Walter may very well have been made up by George for his marriage certificate, not an uncommon thing to happen if somebody was illegitimate.
Although the certificate stated Walter was deceased, did it also give an occupation for him? and who were the witnesses?
It's ok, I realised you had already given that information.
