About the name Hilario
Hilario belongs to the Spanish tradition. Its roots are documented, even though its precise meaning is not recorded in the standard references — an honest gap we prefer to a confident guess.
In the United States, Hilario first appears in Social Security records in 1885. It climbed to its best-ever rank of #840 in 1929, and in 2024 32 babies received the name — 4,651 in total since 1880. Those are the official counts, not estimates.
