About the name Isidro
Isidro 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, Isidro first appears in Social Security records in 1885. It climbed to its best-ever rank of #787 in 1984, and in 2024 92 babies received the name — 8,120 in total since 1880. Those are the official counts, not estimates.
