Hi Jane, Unfortunately - Alberta considers vital events - Birth,Marriage ,Death - as private - and has not indexed any information online.
Ancestry & Family search org. do not have access to this information - unless it is submitted by family -
Some other Provinces have provided Indexes to the Vital events - but limited to what they consider can now be considered Public Record.
Census records - are now available to 1921 - no further.
If they lived in the Camrose area - passed away in Camrose -
Perhaps contacting Cemetery - offices may be of help

Wishing you much luck, Stella
