About the name Lourdes
Lourdes 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, Lourdes first appears in Social Security records in 1916. It climbed to its best-ever rank of #532 in 1963, and in 2024 62 babies received the name — 14,744 in total since 1880. Those are the official counts, not estimates.
