Not a good start researching Ivor as the Commonwealth War Graves Commission website list him as J M Wakefield.
Soldiers That Died in the Great War show his name as Ivor and that he was born in 'British West India'. I also payed a visit to his grave in Richmond Cemetery in South West London and his name is commemorated on a family grave as 'Cadet Ivor Wakefield, RGA, 1897-1917'.
So a note to the CWGC to see if his details can be checked and amended.
He does not appear to have qualified for any war medals as he only served at 'home' and was attached to the Royal Field Artillery (RFA) as noted in SDGW.
Next on the list is ordering a death certificate to find out how and where he died.
