L-Cpl John Thomas Longden, 13234, 10th Battalion York and Lancaster Regiment, was killed in action in France on April 28th, 1917. Although he is included on the Luton Roll of Honour, he may not have lived or worked here and his connection appears to be that his mother, Eliza, had moved to live at 6 Church Street, Luton, a short time before his death.
L-Cpl Longden's connections appear to be almost entirely with the Rotherham area of Yorkshire, where both he and his parents were living when the 1911 Census was compiled.
