From Mac Lochlainn — son of Lochlann ('Norseman', 'Scandinavian'). The Mac Lochlainn were a sept of the Cinéal nÉogain of the Uí Néill federation, distinct from the O'Neills proper, with their seat at Inishowen in north-west Donegal — the peninsula between Lough Foyle and Lough Swilly. Through the 11th and 12th centuries the Mac Lochlainn briefly displaced the O'Neills as the dominant Cinéal nÉogain dynasty, producing two high kings of Ireland.
The history of McLaughlin
Domhnall Mac Lochlainn (d. 1121) made himself the dominant northern lord by 1100 and was acknowledged High King of Ireland with opposition until his death. His great-grandson Muircheartach Mac Lochlainn (d. 1166) was the most powerful Irish king of the mid-12th century, ruling from Tír Eógain and binding most of Ulster, Connacht and Leinster into nominal submission, before his defeat and death at Leitir Lúin in 1166 against Donnchadh Ó Cearbhaill of Airgialla. The political vacuum he left was the immediate opening Diarmait Mac Murchada exploited a year later by inviting the Norman intervention of 1169.
After 1166 the Cinéal nÉogain leadership reverted to the O'Neills and the Mac Lochlainn declined into a regional Inishowen lordship. They lost their lands in the Plantation of Ulster after 1607, but the surname remained densest across Inishowen and the wider north-west, and travelled with the Donegal-Derry-Antrim diaspora to America (Pennsylvania, the Carolinas, the Rust Belt) and to Glasgow and Liverpool in the 19th century. The Anglicised forms McLaughlin (American), McLoughlin (modern Irish) and Loughlin (uncapitalised Mc) are the commonest spellings.
