Newton Bernard's obituary is in the Lethbridge Herald, June 19 1941.
Headline is "Chief Accountant of Liquor Board Dies". Bernard Guthrie of Edmonton, 46, chief accountant of the Alberta Liquor Control Board for the past 11 years died in hospital following a major operation. Mr Guthrie had been employed by the control board for the past 17 years. Born in Scotland, Mr Guthrie was a veteran of the First Great War. He is survived by his widow and one son.
Unfortunately, the obituary doesn't name the son. (but you posted his name earlier... it appears to be in Newton Bernard's military record)
