Anglicized form of both Coinneach and Cináed. This name was borne by the Scottish king Kenneth (Cináed) mac Alpin, who united the Scots and Picts in the 9th century. It was popularized outside of Scotland by Sir Walter Scott, who used it for the hero in his novel 'The Talisman' (1825). A famous bearer was the British novelist Kenneth Grahame (1859-1932), who wrote 'The Wind in the Willows'.
