OK, I found that too. Did he stay in Niagara Falls?
He died in 1973, do you know where? Maybe we could find an obit in a local paper?
Do you know where he was buried? The cemetery might have further information, like next of kin, family he might share a plot with, etc.
If he died on Ontario, you can order his death record, it might have his parents names on it. Initials are hard to work with.
