About the name Sirena
Sirena belongs to the English & American 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, Sirena first appears in Social Security records in 1966. It climbed to its best-ever rank of #1253 in 1995, and in 2024 35 babies received the name — 3,147 in total since 1880. Those are the official counts, not estimates.
