Thank you so much everybody, ie JenB, Priscilla, Alders and lizdb, your speedy responses to my first ever post were incredible. Hilda Lizzie WHIDDETT's dob was 14th April 1903, so it does seem pretty certain she adopted the surname of her uncle and aunt (ie Dadd), and that she married George HARVEY in 1946, and died in 1985.
I'm so sad that my dear old gran (who died in 1976), didn't know. She could have met her had this information been available back then. Aged just 14yrs when her mother died, my gran brought up 8 of her younger siblings, only to then see three brothers, a sister and a brother-in-law killed in WW1.
Marrying so late, I doubt if Hilda had any children? Do any of you know where she was married and where Hilda Lizzie Harvey died please?
