About the name Cecilio
Cecilio 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, Cecilio first appears in Social Security records in 1909. It climbed to its best-ever rank of #1351 in 1945, and in 2024 15 babies received the name — 2,402 in total since 1880. Those are the official counts, not estimates.
