The story of Julio
The name begins with the gens Iulia, one of the old patrician families of Rome, whose most famous member gave his name to the month of July — julio in Spanish. Latin Iulius passed into the Romance languages, and where Italian kept Giulio and French clipped it to Jules, Spanish and Portuguese arrived at Julio and Júlio. From Spain it traveled across the Atlantic and became thoroughly at home in Latin America, and from there into the United States, where it has been on the records since the nineteenth century. The Roman spine of the name is still visible in the spelling: change one letter and you are back in Latin.

from the Roman family name Julius; meaning debated
Two serious readings compete for Julius. The Roman Julii themselves traced their name to Iulus, the son of Aeneas in Roman legend. Scholars have also connected it to the Greek ioulos, 'downy-bearded', hence youthful. Neither has won, and the name carries both.
