About the name Allan
Allan belongs to the Irish & Celtic 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, Allan first appears in Social Security records in 1880. It climbed to its best-ever rank of #115 in 1940, and in 2024 283 babies received the name — 96,230 in total since 1880. Those are the official counts, not estimates.
