 The MacLean family had been granted land in Jura in 1390, by the MacDonalds, and in 1493 had thus been seen as the natural replacement for them, leading to a branch of the MacLeans being granted Dunyvaig Castle by king James, and expanding into Islay.Naturally, the restoration of the MacDonalds created some hostility with the MacLeans; in 1549, after observing that Islay was fertile, fruitful, and full of natural pastures, with good hunting and plentiful salmon and seals, Dean Monro describes Dunyvaig, and Loch Gorm Castle ""now usurped be M’Gillayne of Doward""..The dispute continued for decades, and in 1578 the Macleans were expelled from Loch Gorm by force, and in 1598 their branch was finally defeated at the Battle of Traigh Ghruinneart.
