WW2 Soldiers info

[adicol]

Hi

I am trying to ascertain what became of my Grandads best friend.
He was born 1918 in Pontypridd, and was called Desmond Cummings.
I believe he would have fought in the 2nd World War, but not sure of which regiment and which force etc.
I did a search for him on Ancestry, but nothing came up at all that is him...not even his birth (which, I found on there!)I have also searched CWGC and National Archives....where now do I go???

Thanks

Colleen
