From Greek legend. Cassandra was a Trojan princess blessed with the gift of prophecy but cursed with the fate that nobody would ever believe her. She was brought back to Greece as a captive concubine by Agamemnon, but met her death at the hands of his jealous wife Clytemnestra. Although it was never generally popular, this name was in occasional use from the Middle Ages until the 18th century, and has recently been revived by parents looking to the pages of classical mythology for distinctive names.
English, Scottish, and French: status name for a young servant, Middle English and Old French page (from Italian paggio, ultimately from Greek paidion, diminutive of pais ‘boy’, ‘child’). The surname is also common in Ireland (especially Ulster and eastern Galway), having been established there since the 16th century.
