September 2, 1897 in St Albans , Hertfordshire, is what i have for her, Anne
Dear Anne,
I believe this may be your Florence:
Birth: Mar qtr 1877, BOXALL Florence, Hambledon 2a 134
(FreeBMD)
If you could obtain a copy of her birth certificate it would confirm her parents and I probably will be able to help you further.
Do you have a copy of her marriage certificate, that may give her age and father's name which you can compare with the birth certificate.
Here is the marriage entry if you don't have the marriage certificate:
Marriage: Sep qtr 1897, BOXALL Florence, St. Alban's 3a 1029
I look forward to being able to assist you again soon.
Kindest regards
Ronnie
