Thanks All,
mmm45 - The medal roll of individuals entitled to the War Badge states that he did serve overseas and it also lists his batallion, or at least I think it does; The roll states it is for the King's Liverpool Regiment, and lists others who were all in the 3rd Batallion or Depot as their unit of discharge. Hope I'm reading this right. I'll have to check the National Archives for this other card. The other information you gave is useful too, thanks.
philipsearching - that's interesting, him being a L Corporal as everything else I've managed to find says he is a Private. Wonder why that would be!?
Newburychap -I thought I had a copy of the medal roll from Ancestry - that's what the title says 'Roll of Individuals entitled to the "War Badge". Am I looking at a different thing, or just getting matters confused? No wonder I need to ask for help and advice, what seems straight forward/simple at first is obviously not to me (I'm thick when it comes to all this stuff!!!)
Thanks again all for so much information and help.
Might also be worth me mentioning (I totally forgot, sorry) that he appears on the 1901 census as Edwin Newby, in the Orford Barracks - Warrington, in the Malitia Liverpool Regiment as a general labourer. Don't know if this would be in any way linked to his service in the King's Liverpool; would he be a reservist if he was in the 3rd batallion then, and sign up again at the outbreak of war?
Too many questions, I'm sorry
