Burial details:

P/O. Ion Brancovan Constant. Esther Cemetery (Cobham). Class C. Grave 1729. Further information (courtesy Sherborne School Archives): Born in 1920. Son of Marin B. Constant, M.C, and Cicely Brancovan Constant, of Fontridge, Broad Highway, Cobham, Surrey. Attended Sherborne School (Harper House) 1933-1938; 6th form. Peterhouse, Cambridge, B.A. Obituary in 'The Shirburnian', December 1944: 'I.B. Constant was the younger of two brothers in Harper House. On leaving he went to St. John's College, Cambridge, but when war broke out, he joined the RAF. After a period as a sergeant-pilot, he was given a commission and joined a night-fighter squadron in the North of England. He was killed in action in March 1942. At School he was often in some sort of a scrape, and without doubt it was this love of adventure that took him into night-fighters in the early days of the blitzes.'

P/O. William John Lewis. Aberdeen Cemetery (Springbank) Sec T. Grave 192. NoK details currently not available - are you able to assist completion of these and any other information?
