I started to trace my grandfathers war record. Very awkward, WW1, volunteered and signed up in Ireland. Know he was in the Royal Leinsters and have one or two pics of him in uniform. He never spoke of the war (I was probably too young to be interested), but I believe he was at The Somme and that he was gassed. No-one in family has any records, letters, medals etc.
Got what I believe is his service record card but it is quite vague.
Just have to keep digging.
