Thank you so much for this info. I did have a look at the LDS site but obviously not in the right place, however, after struggling with the revised format I gave up. I can't find her on the BMD though which is strange. At least that is one more box ticked! Thanks again, Jan

The birth of Florence Elizabeth is registered. This entry from Glos BMD:
Child Surname Child Forename Father Surname Mother Surname Mother's Former Name Year District Office Register Entry
DEAN Florence Elizabeth DEAN DEAN BAKER 1860 Forest of Dean Westbury on Severn, Newnham 20 357

It would appear that it has been indexed incorrectly in the GRO Index. I suspect that this is the one being sought.
Births Jun 1860
Green Florence Elizabeth Westbury on S 6a 184

This is from the 1861 Census:
Household Number Given Name Surname Relationship Age Estimated Birth Year Gender Birth City Birth County Birth Country
91 George B Dean Head 26 1835 Male Kingsinford Staffordshire England
91 Mary A Dean Wife 26 1835 Female Kingsinford Staffordshire England
91 Florance E Dean Daughter 11/12 1860 Female Kingsinford Staffordshire England

It would appear that George Bayliss Dean died in 1867:
Deaths Jun 1867
Dean George Bayliss 33 Stourbridge 6c 108

and Mary Ann remarried:
Marriages Mar 1870
DEAN Mary Ann Stourbridge 6c 204
VALLANCE Joseph Stourbridge 6c 204

Not found them in the 1871 Census. This is the 1881:

This is the birth registration of Alfred Wooldridge Dean:
Births Mar 1879
Dean Alfred Wooldridge Dudley 6c 133

Florence's marriage in 1884:
