About the name Fannie
Fannie belongs to the 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, Fannie first appears in Social Security records in 1880. It climbed to its best-ever rank of #47 in 1881, and in 2024 42 babies received the name — 85,511 in total since 1880. Those are the official counts, not estimates.
