Occasionally bestowed in modern times in honour of the French emperor Napoleon Bonaparte (1769–1821), who was born in Corsica into a family that was ultimately of Italian origin. Napoleone is a rare Italian given name, used in Abruzzo, Latium, Umbria, and Tuscany. It is probably of Germanic origin, perhaps connected with the name of the elvish Nibelungen ‘sons of the mist’ (compare modern German Nebel). It was later altered by association with Italian Napoli ‘Naples’ (Greek nea polis ‘new city’) and leone ‘lion’.
South German, Swiss, and Jewish (Ashkenazic): topographic name for someone who lived in a street in a city, town, or village, Middle High German gazze, German Gasse, Yiddish gas ‘street’, ‘side street’.
