MacDonnell of Antrim

The MacDonnells of Antrim (Gaelic: Mac Domhnaill; Ulster-Scots: M'Donnals), also known as the MacDonnells of the Glens, are a branch of the primarily Scottish-based Clan Donald in Ireland. 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.
