About the name Adelaida
Adelaida 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, Adelaida first appears in Social Security records in 1889. It climbed to its best-ever rank of #1034 in 1899, and in 2024 92 babies received the name — 3,111 in total since 1880. Those are the official counts, not estimates.
