I am searching for the British War Service Records of John George Seeley 1887 - 1958. Reg No 305310, 5th London Regiment. Would like to know what he died of, as he was one of the many suffered from the mustard gas in the Somme and believe sent home. I am unable to get past what I have here, as I don't know where to look. If anyone can help it would be much appreciated. Cheers M
