Hi, What time frame are you researching? Even aprox may help others help you.

An Obituary may have been published - some are informative - may show names and locations of other family members etc.

Depending on requirements of the time will show
date and place of birth - names of parents including maiden name of the mother [as known to informant ]
Marital Status. Name of Spouse. Occupation etc.
Do you know where the family had lived? in Alberta?
