The southern parts of the Kingdom of the Isles had become the "Lordship of the Isles", ruled by the MacDonalds (another group of Somerled's descendants). Amy married the MacDonald leader, John of Islay, but a decade later he divorced her, and married the king's niece instead (in return for a substantial dowry). As part of the divorce, 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, John granted Lordship of the Uists to Ranald's younger brother Godfrey and made Ranald Lord of the remainder of Garmoran.
