About the name Nereida
Nereida 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, Nereida first appears in Social Security records in 1936. It climbed to its best-ever rank of #986 in 1981, and in 2024 9 babies received the name — 3,697 in total since 1880. Those are the official counts, not estimates.
