There are many John Henry Edwards births but this looks very much like his:

Surname First name(s) District Vol  Page
Births Sep 1889   (>99%)
Edwards John Henry P C Eton 3a 630

The 1891 census corroborates this by recording that he was born in Iver.  His age was transcribed as 8, but the enumerator’s form does not show this, has the age blocked out by a X and might even be a mere 1.

His death in Burke is very cryptic: : “Sir John Henry Priestley Churchill Edwards, 3rd Bt; b 7 July 1889; T/Lt 4th Bn Rifle Bde, Lt 23rd Bn London Regt TF, served WW II with Australian Forces; das unm 13 Nov 1942”.

Then this entry is to be found on the Commonwealth War Graves site:

  In Memory of
  Corporal JOHN HENRY EDWARDS

  Q119901, A.C.M.F. 8 D.R.O., Australian Headquarters
  who died age 53

  Remembered with honour

This has to be him: the age and death date are the same as the Burke information.
