Lord of Islay

Lord of Islay was a thirteenth- and fourteenth-century title borne by the chiefs of Clann Domhnaill before they assumed the title "Lord of the Isles" in the late fourteenth century. The first person regarded to have styled themself "Lord of Islay" is Aonghus Mór, son of the eponymous ancestor of the clan, Domhnall mac Raghnaill. The designation "of Islay" was frequently used by these lords and later members of the clan.
