bishop. Born at Cashel of the royal family of Munster, Kessog went to Scotland, became a monk and eventually a bishop in the area around Loch Lomond. Luss was the principal centre of his cult with a sanctuary granted by Robert Bruce, his traditional residence was the Monks' Island in the Loch. Kessog is said to have been murdered by assassins at Bandry, where a heap of stones known as St Kessog's Cairn once stood. Part of this was removed during road-making in the 18th century and a stone statue of Kessog was found inside it. Several churches in different parts of Scotland are dedicated to him. Feast: 10 March.
