About the name Keiko
Keiko belongs to the Spanish and 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, Keiko first appears in Social Security records in 1922. It climbed to its best-ever rank of #2471 in 1941, and in 2024 23 babies received the name — 1,153 in total since 1880. Those are the official counts, not estimates.
