Nickname from Middle English flo(u)r ‘flower’, ‘blossom’ (Old French flur, from Latin flos, genitive floris). This was a conventional term of endearment in medieval romantic poetry, and as early as the 13th century it is also regularly found as a female personal name.
Metonymic occupational name for a miller or flour merchant, or perhaps a nickname for a pasty-faced person, from Middle English flo(u)r ‘flour’. This is in origin the same word as in 1, with the transferred sense ‘flower, pick of the meal’. Although the two words are now felt to be accidental homophones, they were not distinguished in spelling before the 18th century.
