From the Old French form of the Greek name Eugenios (from eugenēs ‘well-born, noble’). This name was borne by various early saints, notably a 5th-century bishop of Carthage, a 7th-century bishop of Toledo, and four popes. It is sometimes used as an Anglicized form of Irish Eóghan and has also been used as an Anglicized form of the Irish name Aodh.
Variant spelling (mainly French and South Indian) of Emanuel, which was used in the Middle Ages by Christians as an alternative name for Christ. The name was also borne by a 3rdcentury martyr. Among Christians in India it is used as a given name, and in the U.S. it has come to be used as a last name among families from southern India.
