HMM - reading your other post and this one, I am a bit confused. I see that you have his death in California in 1972 after a name change and several marriages.

A very interesting fellow is your Frank!!
However, other information you found says he was married to someone named Olive, lived in Toronto in 1974 (voters list) and died in Toronto in 1981.
I found the 1981 obit...
Frank C Hazeldine died a the Toronto East General Hospital on Sept 16, 1981. Husband of Olive Turner. Father of Francis in Boston. Lists stepchildren too. Brother of Marnie and Ethel in USA. Buried at Resthaven Memorial Gardens.
