The story
Apparently brought up in English literature by James Fenimore Cooper in The Last of the Mohicans (1826), but compare a female heroine of this name in Jean-François Marmontel's Les Incas (1777) and the Ancient Greek epithet Κόρη (Kórē) for Περσεφόνη (Persephónē). It could also refer directly to κόρη (kórē, “maiden”).
