I had an Aunt(Loretta Rita Cormier) whose Mother or Grandmother was a Margaret Comier.I need to find out who she was married to and if there is any information on Birth, Marriage, or Death available?

Loretta Cormier married my Uncle Alvin Joseph O'Keefe April 19,1954 in Lindsay, Ontario Canada. Loretta was born December 31,1933 in Moncton, New Brunswick, Canada. Loretta died February 26,1990 in Lindsay Ontario, Canada. Alvin and Loretta O'Keefe had5children:Bernadette,Betty,Rachelle,Jean Ann, and Danny.

If anyone has any details or corrections on this subject, I'd appreciate any help you may know on the subject.

I do not have any documentation that reflects the information I have.
Thanks in advance
Betty
