Meaning and history
Latinized form of the Greek name Ἅγνη (Hagne), from Greek ἁγνός (hagnos) meaning “chaste.” Saint Agnes was a virgin martyred during the persecutions of the Roman emperor Diocletian, and her name came to be associated with Latin agnus “lamb,” which led to her frequent depiction with a lamb at her side. Because of her fame, the name spread through Christian Europe and was highly popular in England from the Middle Ages to the 17th century, then revived in the 19th century and common into the 20th before declining after the 1930s; it last appeared in the American top 1000 in 1972.
Agnes moved from #966 to #988 for girls between 1971 and 1972. Its highest annual birth count came in 1918, with 5,291 births.
