List of Famous people named Aonghus

Aonghus Óg Mac Domhnaill, or Angus Og MacDonald, was a fourteenth-century Scottish magnate and chief of Clann Domhnaill. He was a younger son of Aonghus Mór mac Domhnaill, Lord of Islay. After the latter's apparent death, the chiefship of the kindred was assumed by Aonghus Óg's elder brother, Alasdair Óg Mac Domhnaill.

Aonghus Mór mac Domhnaill was a leading figure in the thirteenth-century kingdoms of the Isles and Scotland. He was a son of Domhnall mac Raghnaill, the eponym of Clann Domhnaill, a branch of Clann Somhairle. Aonghus Mór appears to have succeeded his father in the mid part of the thirteenth century. At the time, the rulers of the Isles were fiercely independent of the Scottish Crown, and owed nominal allegiance to the distant Norwegian Crown. Aonghus Mór's first certain appearance in the historical record seems to evince his involvement in aiding native Irish kindreds against the consolidation of Anglo-Irish authority in the north-west Ireland. Such cooperation could have been undertaken in the context of overseas kindreds like Clann Domhnaill constructing Irish alliances to gain assistance against Scottish encroachment.

Aonghus mac Somhairle was a leading member of Clann Somhairle. He was a son of Somhairle mac Giolla Brighde, King of the Isles and Ragnhildr Óláfsdóttir. Other sons of Somhairle and Ragnhildr include Dubhghall, Raghnall, and possibly Amhlaoíbh. Aonghus' father was the common ancestor of Clann Somhairle. The succession of this kindred upon Somhairle's death is uncertain. The Clann Somhairle imperium appears to have spanned from Glenelg in the north, to the Mull of Kintyre in the south. It is possible that Aonghus came to rule in the north, with Dubhghall centred in Lorne, and Raghnall in Kintyre and the southern islands.
