Where the Leo surname comes from
Leo means “lion”: Léōn in Greek, leo in Latin. The Greeks and the Romans already used it as a personal name, a wish for strength and courage. In the Middle Ages the name Leo, or Lio, was common all over the South.
The son of a man called Leo became “Leo’s boy,” until the father’s name stuck to the whole family. This is why the surname has no single founder: every town had its own Leo and his children.
A pope and a musician
The most famous Leo of ancient times was Pope Leo the Great, who in 452 went out to meet Attila as he marched on Rome. Many centuries later, a boy from Apulia left for Naples and became one of the fathers of its great school of music. The PDF tells their stories, and what they have to do with your surname.
Where the Leos live today

Yet the town where it ranks number one is in Campania: Siano, in the province of Salerno. The families in Lombardy tell the story of the 20th-century trains to Milan.
