Hi, What time frame are you researching? Even aprox may help others help you.
What research have you already done ?
Is your Grandfather Theodore Wilbur BAKER still living ?
If Not - do you know When? Where ? he passed away.
An Obituary may have been published - some are informative - may show names and locations of other family members etc.
Genealogical Registration of Death
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?
Cheers, Stella
