My paternal grandfather died on May 10, 1935 and the family was always silent as to where he died. He was suffering from depression due to an accident that took his right forearm. We always thought he died in a mental health facility but were never told. I checked with the hospitals in London and St. Thomas and there was no record of him. Was there a hospital in Gravenhurst where he might have been a patient in 1935? How can I find out if that is where he died?

Start by getting a copy of his death registration. It will name his place of death. If he did in fact die in a hospital you'll find out which one.
