Hi Karen, If no one can help - perhaps contacting a Public Library in Red Deer Alberta - They may hold newspapers in their collection.
I did search Red Deer Advocate - Obituaries online -
http://www.reddeeradvocate.com/obituaries/ found other RITCHIE obits - but not for Blanche RITCHIE nee LETTNER
Blanch RITCHIE nee LETTNER age 89 - passed away at Eyebrow Sask. ?
Perhaps an obituary had been published - in that location.
