so thomas warrington was born in Luton, Bedfordshire, England in 1889.the 1901 census has him as a scholar with the 1911 census has him as a medical student,.iv had a quick look on the London Gazette and it has him being announced as a Lt on the 21st april 1914 with the rank being confirmed on the 16 june 1914.i cant find any other entries but the LG is a nightmare to use so il give it a try later! he was there with the BEF so its a nice group to a officer who was there at the very start of the war!cant see on the medal car dif he was entilted to the clasp ut theres a good change he was!
i couldnt find a date of death but after looking on the Uk medical register,hes not listed after 1955 so either he retired or was deceased after this year! iv posted a pic of his medal index card as the one you got off the national archive is probably black and white and i dont think its has a scan of the back! if i find any more info il post it for you!!
