MacLoughlin, sometimes thought to be a celtic name is in fact of Danish origin according to recent research. The Danes have many connections with Ireland spanning from pre-English times. The MacLoughlins, or sons of Loughlain were kings, believed to preside in Inishowen, Donegal. Reports of the celtic era tell of them joining the O’Neils in a fight for supremecy against the O’Donnels; ancient records however tell of the murder of MacLoughlins and their men by the warring O’Neils and O’Donnels who joined forces in order to take over Inishowen.
