My grandfather Alfred Etheridge born 1898 in Wellington, Surrey served in the London Regiment during 1917-1918 period. I have his record from the British Army WWI Medal Rolls Index Cards, 1914-1920 and UK, WWI Service Medal and Award Rolls, 1914-1920 showing what regiments he served in over what time. I am wondering if there is a full army service record for him showing enlistment and discharge information and any other related information. His theatre of war was 1a which was Flanders according to the above record. Other than that I could research the 1/19th London Regiment war diaries I guess?
