Hi Debbie, The reason I ask about an Alberta Connection.
You have posted to the General Message Board for Alberta Canada.
If your research is in Ontario - Best to Post to Message Board There.
Where in Ontario did Bruce KUHN pass away - you have the obituary !!! - Search the City Directories - or telephone books prior to his year of death.
Some obituaries are very basic - really only a notice of death - others a bit more informative.
Many people are in the same situation as you are - perhaps over time - your mother might give you some information -be kind, not demanding - when asking., there are others who don't even have names to follow up - because of family break downs etc
Cheers & Good Luck, Stella
