About the name Deirdre
Deirdre 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, Deirdre first appears in Social Security records in 1921. It climbed to its best-ever rank of #333 in 1961, and in 2024 10 babies received the name — 16,831 in total since 1880. Those are the official counts, not estimates.
