time, Castle Tioram was built, in Loch Moidart, as the principal seat of the Lordship of Garmoran. Most of the remainder of the Kingdom of the Isles had become the Lordship of the Isles, ruled by the MacDonalds, whose leader, John of Islay, married Amy. After the birth of three sons, he divorced Amy and married the king's niece, in return for a substantial dowry. As part of the arrangement, John deprived his eldest son, Ranald, of the ability to inherit the Lordship of the Isles, in favour of a son by his new wife; as compensation, he made Ranald the Lord of Garmoran. However, at the end of the 14th century, on Ranald's death, his sons were still children, and Ranald's younger brother Godfrey took the opportunity to seize the Lordship of Garmoran. Furthermore, the heirs of Ranald's other brother Murdoch now made their own claim. This involved Godfrey's family (the Siol Gorrie) and those of his brothers in a great deal of violent conflict which is not described in much detail in surviving records. In 1427, frustrated with the level of violence generally in the highlands, together with the insurrection caused by his own cousin, King James I demanded that highland magnates should attend a meeting at Inverness. On arrival, many of the leaders were seized and imprisoned. Alexander MacGorrie, son of Godfrey, was considered to be one of the two most reprehensible, and after a quick showtrial, was immediately executed. As Alexander had by now inherited Godfrey's de facto position as Lord of Garmoran, and in view of Ranald's heirs being no less responsible for the violence, King James declared the Lordship forfeit. Lairdship grants In 1469, James' grandson (James III) granted Lairdship of the lands of Garmoran and Uist to John, the Lord of the Isles. In turn, John passed it to his own half-brother, Hugh of Sleat; the grant to Hugh was confirmed by the king in a 1493 charter. The violence that led to Alexander's execution had brought the Siol Gorrie to the brink of extinction, and after Alexander's death they played no further part in Moidart's history. Ranald's heirs (Clan Ranald) disputed and fought against the charter. Following Hugh of Sleat's death, in 1498, and for reasons that are not remotely clear, his son John immediately resigned, transferring all authority to the king. In 1532, the king granted Moidart to the leader of
