I've got a feeling Captain Lowry may be Archibald Lowry, a founder of the Royal County Down Golf Club that hosts the British Senior Golf Championships, and a cousin of Sir Gerald Lowry who was a Harley Street physician. Sir Gerald was the first British officer to be wounded during WWI and was blinded but continued to practice medicine, sail at Crewe and ski at St. Moritz. But can't get any further leads.
Bob Wallace might be Col. Robert Hugh Wallace , C.B., of Myra
Castle, CO. Down.
