About the name Jacó
Jacó belongs to the Portuguese 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, Jacó first appears in Social Security records in 2004. It climbed to its best-ever rank of #9988 in 2006, and in 2024 7 babies received the name — 61 in total since 1880. Those are the official counts, not estimates.
