I think I have found Cissie May....
She married Herbert Stanley Cowell in Wellingborough, Northamptonshire in 1916 (see FreeBMD).
Herbert Stanley Cowell died in WW1 - 27 May 1918. Commonwealth War Graves Commission site says he is commemorated on the Soissons War Memorial in France
https://www.cwgc.org/find-records/find-war-dead/casualty-details/725808/HERBERT%20STANLEY%20COWELL/Cissie married again to Charles Leonard Hurd in Bath in 1922 (see FreeBMD)
Cissie and Charles Leonard Hurd had 3 children, in Headington Oxfordshire - (see FreeBMD - surname Hurd, mother's maiden name Brown)
Leonard Percy Hurd - 1923-1991
Phyllis Daphne Hurd - 1926-1998
G C Hurd - 1927
1939 - Cissie is a widow again - in Bath, Somerset. Probably can't post details.
Looks like Charles Leonard Hurd died in Headington in 1927 (see Free BMD)
Cissie May Hurd died in Bath, Somerset in 1978. (FreeBMD)
