Looking for an Ernest Mason who died in a veteran's hospital in Cobourg in March 1920. He may have been English and been married to a Mary Jane Rathburn nee Black of Alderville. He had a daughter and his son was born the month after he died. I am told his cause of death was in relation to a gas attack during World War I. I found a record for an Ernest Albert Mason born May 4, 1878 and I am not sure if this is the same person. Thanks.
