I don't have access to 1916 Census - but that may prove helpful.
Check Alberta GenWeb Local History Books * doa google search for site
perhaps you will recognize some family names.
The family were in Alberta for a number ofyears - then left for where?
Perhaps posting to that area - may also prove helpful with your research.
Cheers & Good Luck, Stella
