Niall

Niall is an Old Irish masculine name whose precise etymology has been debated, with proposed roots including a Celtic element meaning champion or cloud, and a possible connection to the Old Irish word nél, meaning cloud. The name was borne by the semi-legendary High King Niall of the Nine Hostages, ancestor of the powerful Uí Néill dynasty that dominated medieval Ireland, making it one of the most historically significant names in Irish tradition. Its anglicized form Neil spread widely throughout Britain and beyond, and related cognates include Neal, Neill, and the Scottish Gaelic Nèill.
