Meaning and history
Julius is a Roman family name possibly derived from Greek ioulos, meaning "downy-bearded," or connected with Jupiter. The patrician family claimed descent from Aeneas's son Julus, and its greatest member, Gaius Julius Caesar, conquered Gaul, became dictator after civil war and was assassinated in the senate. Despite use by early saints and a pope, the name was rare in the Middle Ages before its Renaissance revival in Italy and France and later arrival in England.
Julius moved from #386 to #424 for boys between 2024 and 2025. Its highest annual birth count came in 1918, with 1,416 births.
