Agnes Mary CUNNINGHAM (née KELLY, aka Agnes Mary STUART) [1877-1944]
21 Sep 2015 UPDATED with details from Chriscalder's comment below.
John Black's list gives Mrs Cunningham's year of birth as 1889, and date of death as 25 July 1944.
Philip Cracknell writes that:
[Robert Cunningham] was married to Agnes Cunningham and shared a billet (5 P4) with her in Stanley Camp. I was always puzzled by the age difference. She died in Camp but date of birth was 1877. She had an married daughter in Camp Mrs M J Stuart). Robert and Mrs Stuart both protested the age stated in the Medical Rocords (which I have seen).
