Julio
Meaning
“Spanish form of Julius, a Roman family name of debated meaning, possibly Greek ioulos, 'downy-bearded'”
The story
Julio is the Spanish form of Julius, the family name of Rome's most storied clan: the Julii claimed descent from Iulus, son of the Trojan hero Aeneas, and scholars still argue what the name originally meant, with downy-bearded the traditional guess. The modern bearers need no argument. Julio Iglesias holds the Guinness title of best-selling male Latin artist, Julio Cortázar's Hopscotch became a landmark of the Latin American Boom, and Julio César Chávez opened his boxing record with 89 wins and a draw before anyone beat him. The American ledger has carried Julio since the 1890s, about 63,800 boys in all, including roughly 13,800 in the 1990s alone. Brazil's 2022 census counted 327,493 more, ranking it 82nd in the country. An emperor's surname that became a first name spoken warmly across two hemispheres.
