Hello Ady, thanks for such a speedy answer!
That sounds as though it may be him, as my husband now tells me he was born in Loughborough. I wonder what his regiment was - Leicester something or others I expect.
The other grandad was gassed on the Somme in WW1 as well. His name was Albert Clayton born 1989, he died from the same sometime in the 1930's. We don't know anything else about his time as a soldier either - it would be so nice to find out.
Thanks again to you and to anyone else who can give us further info.
