Sorry for delay, my computer crashed on me.
Your gt gt uncle was very young, just checked him out on the CWGC, I see he died at the 3rd battle of Ypres, better known
world wide as Passchendaele, i'll have a look out for his name the next time i visit the Menin gate at Ypres.
As you say, such a waste of a generation.
regards
jim
