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.
This name was popular throughout the English-speaking world in the early 20th century. It staged a comeback in the early 21st century, returning to the American top ten in 2017.
