G'day guys,
The gentlemen you are talking about are my Great Uncles, I am told that their father (Edward) marched the three eldest brothers of the Dormer family down to the recruiting office on the first day of the war in 1914 with one of their cousins along for luck.
Shane, you were right about the Indian connection with Edward. His father joined the 3rd Battalion 60th Regiment in Dublin in 1855, and they then moved out to India where Edward and two sisters were born. On a side note Billy Connolly's Great Grand father (Doyle from Hollywood) joined the battalion at the same time and went out to India too.
My Grandfather was Arthur Dormer William's little brother.
