I do know that Alfred Norton Allen and Josephine Kohn Allen passed away in Ohio, as far as I know they never went to Canada. They are both buried in the Middle Creek Cemetery in Paulding, Ohio along with 4 of their sons John Newton, Clarence Russel, Raymond Arthur, and Charles Robert. Their son, Leroy Earnest, the one my line goes through moved to Tennessee and he and his wife died there.
I'm a little confused by the information you have provided. I'm guessing you are saying that I may be able to find some information by finding death and obituary records?
