Guys,
Can't thank you all enough.
Monica, I had managed to get the service history as I have James war medals so the details you added are correct (correct service number). I guess I am still trying to get to grips with searching as now trying to find the items you have already mentioned, so I can work out the best way to do this. Also got some (although few details) from a book called Coatbridge and the great War, which had all or most coatbridge men from the war.
May look into the Grahames stuff, have primarily been focusing on amguires, from my dads side (now stuck since tracing to Ireland) and Dicherty/Murray on my mums side, which you have all helped with.
Thanks again all... appreciated.
Stovie
