This is a photo of my grandfather Joseph Byrne (on left) from Co Dublin it was taken in 1914-1918 I think in Ireland the corporal beside him is wearing a Victoria Cross we would love to know who he is. I have looked up VC winners from Ireland in WW1 but only some of them have photo's shown. There seems to be 27 Irish born VC winners and a total 167 over various campaign's since it was first given out. I don't know which regiment my grandfather was in. He was wounded but survived the war along with his two brother's in law and died in 1936. Any help would be welcome.
