Notes
The Roll includes this entry for 'George Gardiner' of 50 Westwood Street, who it lists as Private 14892 in the Royal Engineers, but for whom it does not record a date/place of death. (The Roll also lists his brother William John 'Gardiner' of 50 Westwood Street). The Roll misspelt the surname of those two brothers as Gardiner; it was actually Gardner.
Actually, the entry re George Gardner of 50 Westwood Street should not have been included on the Roll at all, as he in fact survived the War.
(On the 1911 Census George Martin Gardner was living at 50 Westwood Street with his parents Eliza and William Samuel Gardner. The Army Service file of that George Martin Gardner, 14892, records that he was attested and joined 'The Buffs' (East Kent Regiment) on 31/8/1918, that he was transferred to 52nd Battalion Royal Sussex Regiment on 26/2/1919, then later to the Royal Engineers 10th Signal Company on 14/9/1919, as Pioneer 618530, and was discharged from the Army in January 1920. Having survived the War, George Martin Gardner married Annie Wortley in 1920, and did not die until 23/8/1972).
It appears the Roll of Honour's compiler mistook the above George Martin Gardner for an entirely different Peterborough man who did die in WW1. The genuine casualty was Private George Martin 3/9695 (son of George Gardner, of 308, Walpole St., Peterborough) who died on 4/3/1917, aged 22, serving in the 2nd Battalion Northants Regiment, and is commemorated on Thiepval Memorial. This was doubtless the George Gardner whose death the Roll's compiler was intending to record; unfortunately, however, they omitted the true casualty's address, service and death details, and instead wrongly included those of the George Martin Gardner of Westwood Street who actually survived the War. [Regrettably, the mistake was later copied onto the 1994 version of the Roll of Honour, and into the WW1 Book of Remembrance in the Cathedral, both of which therefore similarly omit the details of the George Gardner of 308 Walpole Street who died, and wrongly include those of the George from Westwood Street who survived].
(N.B. The Roll is known to include numerous errors, including: misspelt names and inaccurate date/place of death, service number/ rank/ military unit etc; several casualties were mistakenly listed on it twice [i.e. under their true name and also the alias under which they served]; several other men were listed on it due to the mistaken belief they had died, whereas they had actually survived).
