In reply to your letter of the 16th re. my late son – Cecil Barnaby Cook, I send herewith his photograph, the best and only one we possess, will you therefore take great care of it and return to me when finished with  as to the biographical notes.
He was born Nov 12th 1899. Educated at Dulwich College left there Feb 1916 to enter the War Office, in the capacity of assistant in the Aeronautical Designing Department, leaving there on his attaining military age. Taking a commission in the R.N.V.R April 1917 he was sent to France for his training, afterwards qualifying for his pilots certificate at Cranwell. He was ordered to Dover  on Aug 18th preliminary to his leaving there for the Front but was killed there on the 20th owing to his aeroplane, in which he was flying, collapsing at a height of two thousand feet.
He is buried at Hayes (Kent) cemetery.
I am yours faithfully,
