Please can any readers help to clear up mysteries concerning Walter Arthur Leonard Drake?  I need confirmation that he is the son of Walter Drake and Sarah Elizabeth (formerly Smith), who is Walter Arthur Leonard Drake (b Norwich) aged 17 in Norwich in 1911.   The Commonwealth War Graves website has him as L W A Drake.   L W A was a  Lance Corporal in the Hampshire Regiment, and he died 21 Jun 1919 at Kohat, India, and was buried at Kohat and also named on the Delhi Memorial (India Gate).  However, on the Ancestry Legatees website he is Walter Arthur Leonard Drake with the same military information, and his executrix was Laura Olive Lightfoot (with no relationship shown).  I have found nothing about Laura, and can anyone identify her too?
