MacDonnell of Antrim
The MacDonnells of Antrim (Gaelic: Mac Domhnaill), also known as the MacDonnells of the Glens, are a branch in Ireland of the Scottish-based Clan Donald. Initially part of Clan MacDonald of Dunnyveg (Clan Donald South), the MacDonnells of Antrim became their own branch in 1558 when Somhairle Buidhe MacDonnell obtained the lordship of the territory in Ireland from James MacDonald, 6th chief of the Clan MacDonald of Dunnyveg. The MacDonnells of Antrim were a sept of the Clan Donald of the royal Clann Somhairle, that the English crown had attempted to cultivate since the early 14th century in its efforts to influence the course of politics in Scotland. The MacDonnells established a growing presence in Ireland throughout the 15th and 16th centuries, and played a crucial role in the politics of 17th century Ireland. The MacDonnell's achieved much success in Ireland largely to cultural and familial connections to the Gaelic nobility of Ireland. Today the surname is predominantly spelled McDonnell in Ireland and abroad, although many McConnells are also of the same family, as that is the Gaelic pronunciation of the Mac Domhnaill. Most of the leadership of the Clan wrote their name as a variant of McConnell up until the 17th century, including Sorley Boy MacDonnell himself. Many of the present-day McDonnells have a common descent from Sorley Boy MacDonnell. History Origins The MacDonnells of Antrim are descended from John Mor MacDonald, chief of the Clan MacDonald of Dunnyveg. John Mor MacDonald was the second son of Good John of Islay, Lord of the Isles, 6th chief of Clan Donald, through John of Islays second marriage to Princess Margaret Stewart, daughter of King Robert II of Scotland. John Mor MacDonald married Margery Byset, daughter of the Mac Eoin Bissett, Lord of the Glens of Antrim. Although the MacDonnells would a century and a half later claim that her dowry included the lordship itself, this is false because the Mac Eoin Bissetts remained in possession of it into the early or mid 16th century. However following the death in battle, in support of his friends and kinsmen the O'Neills against the O'Donnells, of the last known Mac Eoin Bissett in 1522, the recently arrived MacDonnells appear to have started making their own gains in the region and eventually used the earlier marriage to claim they had rights to the Bissett lordship. The MacDonnells already possessed Dunnyvaig Castle on the Isle of Islay and lands in Kintyre, Scotland. The MacDonnells of Antrim did not become a separate branch of Clan Donald until 1558, when they were part of Clan MacDonald of Dunnyveg, when Somhairle Buidhe MacDonnell obtained the lordship of the territory in Ireland from James MacDonald, 6th of Dunnyveg. 15th century John Mor was assassinated by James Campbell in 1427. John's son Donald Balloch MacDonald, the second 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, 3rd Lord of the
