About the name Cinthia
Cinthia 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, Cinthia first appears in Social Security records in 1946. It climbed to its best-ever rank of #942 in 1996, and in 2024 19 babies received the name — 6,124 in total since 1880. Those are the official counts, not estimates.
