My grandmother lost both her brothers on the Somme.
William was a Corporal and was killed leading a patrol in January 1916 and Walter, his older brother was killed at the end of the battle itself, in September 1916.
There are many sadnesses connected with their deaths, first that two sons from the same family both perished in the trenches, which was by no means unique, another that they are buried only a few km apart, Walter in Pozieres and William in Meaulte and last that neither are buried under their family name. This is because they were from a German family which meant under their actual name they could have served in the engineers, building and repairing, but would not have been allowed a weapon and to fight, so William shortened his family name to Wucher and Walter invented the surname Walker.
I can only imagine the effect on my great grandparents of losing both their sons, on the same battlefield, in the same year, in the same war.
My grandmother was about 16 or 17 when her brothers were killed. She died at the age of 97 and mentioned them often, still missing them both.
