John MacSween

John MacSween (Scottish Gaelic: Eoin MacSuibhne) was a 13th-14th century nobleman. He lost his lands in Scotland and settled in Ireland.

After the defeat of the forces and death of Alexander Og MacDonald, Lord of Islay in 1299 against the forces of Alexander MacDougall, Lord of Argyll, an expedition led by Angus Og MacDonald, Hugh Bisset and John was undertaken against the Lord of Argyll shortly afterwards. During the Wars of Scottish Independence, John entered into the service of King Edward I of England in the hope of keeping alive his family's claim against the Menteiths. In 1310, King Edward II of England granted the ancestral MacSween lands to John MacSween and his brothers, which had been in the possession of Sir John de Menteith. John led an expedition to retake Castle Sween and their territory in Knapdale, however they were defeated. John settled in Ireland.
