Clan MacDonald of Dunnyveg

Clan MacDonald of Dunnyveg, also known as Clan Donald South, "Clan Iain Mor, Clan MacDonald of Islay and Kintyre, MacDonalds of the Glens (Antrim)" and sometimes referred to as "MacDonnells", is a Scottish clan and a branch of Clan Donald. The founder of the MacDonalds of Dunnyveg is Eòin Mòr Tànaiste Mac Dhòmhnaill, a son of Iain Mic Dhòmhnaill (John of Islay, Lord of the Isles) and Margaret Stewart. Members of the Clan actually pronounced and spelled their name "M'Connal" due to the Gaelic pronunciation of the name "Mac Domhnuill" thus giving rise to the surname McConnell and its variants.
History.
Origins of the clan.
The founder of Clan Donald of Dunnyveg and the Glens was Eòin Mòr Tànaiste Mac Dhòmhnaill who was the second son of John MacDonald also known as "Good" John of Islay, Lord of the Isles, 6th chief of Clan Donald and 1st Lord of the Isles through his marriage to Margaret Stewart. Eòin Mòr Tànaiste Mac Dhòmhnaill married Margaret Bissett of the Glens of Antrim. From his marriage he claimed, but did not possess, this territory in Ireland, along with those he already possessed in Islay and Kintyre in Scotland. He and his descendants became known as Lords of Dunnyvaig and the Glens, although they did not possess the latter until the 16th century. Their seat in Dunnyvaig was on the Island of Islay and in the Glens they were seated in Antrim.
15th, 16th and 17th centuries.
Eòin Mòr Tànaiste was assassinated by James Campbell in 1427. His son Donald Balloch MacDonald the 2nd chief led the clan when they fought and won at the first Battle of Inverlochy (1431). This was in support of their cousin Alexander of Islay, Earl of Ross and chief of Clan Donald, 3rd Lord of the Isles.
The third Chief, Sir John Mor with his heir John Cathanach and three grandsons were apprehended through the treachery of MacIain of Ardnamurchan and were executed in Edinburgh for treason. However, MacIain of Ardnamurchan, who had also betrayed Alexander MacDonald of Lochalsh, was himself killed in 1518 by those whom he had betrayed.
On the death of James MacDonald, 6th of Dunnyveg and Antrim, the Antrim Glens were seized by one of his younger brothers called Somerled or Sorley Boy MacDonnell known also as "Sorley Buy". In 1565 under Sorley Boy MacDonnell the Clan Donald of Antrim and Dunnyveg fought the Battle of Glentasie against Shane O'Neill in Ireland. Sorley Buy swore allegiance to James IV of Scotland and his fourth son Ranald was made Randal MacDonnell, 1st Earl of Antrim by Queen Elizabeth.
Much quarrelling took place between Angus MacDonald, 8th of Dunnyveg and his eldest son, Sir James MacDonald, 9th of Dunnyveg this was largely due to the intrigues of the Clan Campbell. Sir James MacDonald led the clan who fought and won at the Battle of Gruinart Strand on the Isle of Islay in 1598 against an invasion force of the Clan MacLean who were led by Sir Lachlan Mor Maclean of Duart Castle who was killed.
Further intrigue by the Clan Campbell brought the downfall of the Clan Donald of Dunnyveg and by 1620 Sir James MacDonald had lost control of Islay and Kintyre. However, during the Civil War the lands were back in the hands of the MacDonalds briefly when they were supporters of James Graham, 1st Marquess of Montrose. A notable member of the Clan MacDonald of Dunnyveg is Alasdair Mac Colla who is famed for his victories with the Royalist James Graham, 1st Marquess of Montrose during Scottish Civil War of the 1640s.
The last chief, Sir James MacDonald, 9th of the Clan MacDonald of Dunnyveg or Clan Donald South died in London in 1626.
