Cecil Jesse Austen GRAY [1908-1968]
Philip notes that Gray was "RNVR, Flag Lt to Commodore Collinson. He had worked before the war as an Accountant in Shanghai."
The earliest mention of him I've found in Hong Kong so far is his appointment to be an acting sub-lieutenant in the Hong Kong Naval Volunteer Force, effective 20th December, 1939. (See item 31 in the Government Gazette for 12th Jan 1940.)
