About the name Petronila
Petronila 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, Petronila first appears in Social Security records in 1888. It climbed to its best-ever rank of #1440 in 1888, and in 2024 8 babies received the name — 64 in total since 1880. Those are the official counts, not estimates.
