Hi, Registration of Death - can be obtained from the Govt of Alberta Vital Statistics Registry Offices
Will show personal information as required at the time - and known by the informant.
May show full date of Birth - names of parents including maiden name of mother. May show time in Canada.which would help with date of arrival in Canada.
The cost $40 cndn.

Obituary if one was published - may be very basic or may show some personal history.

Death registration for Edgar John EVANS b aprox 1926, dcd Halifax NS - will show his correct date of birth - names of parents etc
Who is Nina Gabrille EVANS b 1916? dcd 1936.
Was she the first born to John EVANS and Amelia EVANS nee LOCKE? If so a search for a marriage - a year or so prior to the birth - may prove helpful.
Cheers, Stella
