From the Latin name
Florentius or the feminine form
Florentia, which were derived from
florens "prosperous, flourishing".
Florentius was borne by many early Christian
saints, and it was occasionally used in their honour through the Middle Ages. In modern times it is mostly feminine.
This name can also be given in reference to the city in Italy, as in the case of Florence Nightingale (1820-1910), who was born there to British parents. She was a nurse in military hospitals during the Crimean War and is usually considered the founder of modern nursing.
