About the name Jefferson
Jefferson belongs to the Spanish and English & American 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, Jefferson first appears in Social Security records in 1880. It climbed to its best-ever rank of #253 in 1891, and in 2024 374 babies received the name — 24,141 in total since 1880. Those are the official counts, not estimates.
