About the name Rodolfo
Rodolfo belongs to the Spanish and Portuguese 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. It travels in a few spellings: Germanic.
In the United States, Rodolfo first appears in Social Security records in 1902. It climbed to its best-ever rank of #311 in 1981, and in 2024 124 babies received the name — 33,650 in total since 1880. Those are the official counts, not estimates.
