Neil

Neil is a masculine given name of Gaelic origin. The name is an Anglicisation of the Gaelic Niall which is of disputed derivation. The Gaelic name may be derived from words meaning "cloud", "passionate", or "champion". As a surname, Neil is traced back to Niall of the Nine Hostages who was an Irish king and eponymous ancestor of the Uí Néill and MacNeil kindred. Most authorities cite the meaning of Neil in the context of a surname as meaning champion.
