Florrie

Longer forms could be Florina, Florine, Floriana, Florianne, Floriane, Florimonda, Floretia, Floribel/belle/bella, Florabel/belle/bella, Florimel, Floribeth, Florabeth, Florita, Florisdelfa and Bellaflor.

Florrie was a really common nickname in Victorian and Edwardian England and was also used as a nickname for the name Florissa too which is an elaboration of the name Flora or a variant of Florence and is sometimes used in Dutch as a female version of the boys name floris. I think Florissa and Florrie the nickname are lovely and certainly gives out an ornate Edwardian vibe.
