Hi

Yes I have the medal card that I photocopied at the National Archives (which I assume is the same as the download?!). It just says Alfred Hayden RFA, Sgt, L/40834 Died 2.7.16 and Victory: RFA /336B 47396.
Maybe he didn't enlist in 1915 after all but at an earlier time. The last pre-war occupation I have for him is 1912 when he was working as a railway wagon repairer. I don't know how much time was needed for someone to get to sergeant or whether, out of pure desperation, they just threw people in at the deep end. If he arrived in France at the beginning of May 1916 then he only had two months there before he was killed.
Researching anything related to the First World War is unrelievedly horrific, isn't it?
As far as the Duke of York school is concerned, as I understand it from my grandmother (who's still alive), after Alfred Hayden was killed his mother put her youngest son (my grandfather) into an orphanage and kept the younger daughter. When she remarried after the war she had my grandfather back but, as he didn't get on with one of the stepchildren, he was sent to the Duke of York school and then enrolled with the RA.
Alan: Yes, I agree with you about the brigade diary being a good area for research. I wish I'd looked at it when I was at the NA over the summer but I just ran out of time! I'll check out the online ordering system and see how I get on. How do you know which pages you need to look at?
