Hi Rosie,
Thank you, I have found the suggested Marie Saunders, interesting, only 16 or 17, but she lives only 10 minutes walk away from the road listed as the birthplace for Daphne ...
So it could be her, though I can still find no record of the marriage to Reginald Hamilton, Daphne's father.
You mention - daphne Jiggens -
"Living Sussex (Uckfield area) in 1939, also there a Marie M Lambert bn c1894"
I have been searching but cannot find this record, are you able to give a pointer to help?
