Thanks to everyone for replying.
I am still very unclear to it all.
No I don't have any medals, I never knew him, he died before I was born.
I dont think he stayed on after 1920 as he said coal miner aswell on his marriage cert.
But, saying that, on the electoral registers for 1920 - 22 it said absent for James. So maybe he did continue in the army. But my Gran had two children during those years. Very confusing.
I didn't realise this was as confusing as it is.
Thanks
Angela
