Doire, ‘oak grove’
Originally known as Doire Chalgaich, Derry is now better known in Irish as Doire Cholmcille after St Colmcille founded a monastery there in the sixth century.
The Scottish Gaelic name Domhnall meant ‘ruler of the world.’
McLaughlin - Mag Lochlainn
The name Lochlann in Irish means ‘of the lakes’, and refers to the Vikings who came from the fjords of West Norway.
Originally belonging to the Cineál Eoghain, the McLaughlins were closely related to the O'Neill dynasty. Two kings of Ireland came from the clan, Domhnall Ua Lochlainn and Muircheartach Mac Lochlainn.
