There is a record for marriage for
Victor S Davey and Emily M Barnard
3rd Qtr 1910 Bristol ,Avon Gloucestershire District
Volume 6 a.
If you get a copy of this , it will record the bride and grooms fathers names and occupations, this will help narrow down the family in the census.
Do you have Victors death certificate from 1912 ? If so it will tell you his age at death, to make him easier to find in the English records.
Also Emily's 2nd marriage to Bill Ash. should provide her name and fathers name as well, if you can find a copy of that marriage.
If you have the ships manifest or passenger list of Victor and Emily's journey over to Canada from England, it should list their English address, and also any children they already have , and if they are travelling with any other family members.
Let me know if you find any more details from any of those
