To mark the centenary of the beginning of the First World War on 4 August 2014, the Old Derbeian Society arranged for research to be undertaken into the many names of old boys who had served in the two world wars. Beside including the names, ranks, military service numbers (69 for the First World War and 48 for the Second, 117 in total), details have also been collected of the servicemen's military medal awards, local press reports, and details of where each man is buried or remembered officially. This collection has been assembled into three large volumes, and these were handed to the President of the Old Derbeian Society on 9 November 2014, at the conclusion of the Remembrance Day Service held that year, to be held within the Society's archives.
