Originally a male pet form of James and still so used, especially in Scotland and Northumberland. It is now also found as a girl's name, a feminine equivalent of James, especially in North America, where it is used more frequently for girls than boys. It is famously borne by the actress Jamie Lee Curtis (b. 1958), and is often used in combination with Lee or its variants.
Scottish: Anglicized form of Gaelic Mac Cionaodha or Mac Cionaoith ‘son of Cionaodh’, a personal name which is probably composed of the elements cion ‘respect’, ‘affection’ + Aodh, a Gaelic personal name, originally the name of the Celtic god of fire. The personal name thus probably means ‘beloved of Aodh’.
