Private Harry Hargreaves
528231 Royal Army Medical Corps
Lived at 21 Landsdown Street

Your list doesn't include his elder brother Ernest Hargreaves, also of the RAMC (528294), but he must have left the town when he married in 1916. However, his MSM listing in the London Gazette 9.12.1919 iss.31684 page 15444, gives him as from Burnley. He also survived the war

They had an elder brother Frank who worked during WW1 as a chemist in munitions manufacture in Scotland.
