  Biography
  With his father, he signed the Treaty of Ardtornish in October 1461, which proposed that Scotland be divided between King Edward IV of England and James Douglas, 9th Earl of Douglas. He succeeded to the chieftainship of the clan after his father died at Islay in 1476.
  
  In 1493, with John of Islay being required to forfeit his title of Lord of the Isles and paid homage to King James IV of Scotland, the King garrisoned and provisioned Tarbert and Dunaverty Castle with Royal forces in 1494. Sir John MacDonald, whom the king had recently knighted and to whom and John had rendered homage, retook Dunaverty Castle just as the King was sailing for Stirling. The dead body of the castle's governor was hung over the castle walls in sight of the King and his departing entourage. The King, infuriated by Sir John's actions, declared Sir John a traitor and he was summoned him to Edinburgh for treason.
  
  Sir John Macdonald ignored the summons and continued to reside at Islay. He and his sons were captured through the treachery of his kinsman John MacIan of Ardnamurchan. Sir John, his son John Cathanach and John Cathanach's sons John Mor, John Og and Donald Balloch were tried, convicted of treason and hung on the Burgh Muir in 1499. John Cathanach's remaining son, Alexander, fled to Ireland and became the next chief of the clan.²
