Possibly the A Bainbridge mentioned in 'Evenwood's Heyday' by Elsie Anderson et al, who took part in 'one of the first great battles of the War, which involved 'several of our local lads. This was probably the battle on September 25th in the region of Loos'. A wrote home saying that the 15th Durhams had come out of the battle pretty but they had lost a good many men.
