Notes
The memorial entry states date of death as 23rd April 1917 . No casualties with the given name Simmonds are recorded on that date but a casualty with strong family connections to Southampton is recorded as having died on 28th April 1917 and it is very likely that it is he who is referred to on the memorial .
