Meaning
“Spanish form of Julius, a Roman family name of debated meaning, possibly Greek ioulos, 'downy-bearded'”
The story
The Roman family behind Julio had a story about its own beginnings. The Julii claimed descent from Iulus, the son of Aeneas in legend, and Julius Caesar was a historical bearer of their family name. That ancestral claim does not settle the etymology: Julius may come from Greek ioulos, "downy-bearded," or relate to Jupiter. Spanish made it Julio, alongside Portuguese Júlio and Italian Giulio. Centuries after the Roman genealogy, Julio Cortázar gave readers an unusual way to enter a story. His novel Rayuela, published in 1963, offers an ordinary reading order, a direction table, or an approach left to chance. Paris and Buenos Aires form the book’s geographical sides, but moving through it need not follow a straight line. The reader can open the same volume and take a different route through its chapters, following instructions that make choosing part of reading.

First names given to children born in Poland by year of birth, 2000–2025, from the PESEL population register (Ministry of Digital Affairs); exact spellings count separately (Łukasz and Lukasz are different names), names given fewer than 5 times in a year were left off the list through 2012 and fewer than 2 times from 2013, and the register also counts children born abroad, so its yearly sums run above Poland’s live births. Shares divide by the register’s own published total for the year, never by births. Source: Ministry of Digital Affairs, PESEL register (dane.gov.pl)
Not on the record in Ireland, New Zealand and Scotland: those registries withhold small counts, so rare uses may sit below their floors.
Not on Norway’s list: Statistics Norway lists only first names carried by 200 or more living people, so rarer names are not shown.
