About the name Crosby
Crosby 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, Crosby first appears in Social Security records in 1912. It climbed to its best-ever rank of #578 in 2015, and in 2024 170 babies received the name — 5,714 in total since 1880. Those are the official counts, not estimates.
