The Commonwealth War Graves Commission, 'Soldiers Died' and medal index card give his date of death as 28th September 1916. However, the register of the disposal of his personal effects agrees with the family notices as 29th August 1916. As the first notice was published on 5th September 1916, a little over three weeks before the official date of his supposed death, the official date must be incorrect.
