Loughlin [Lochlainn] (m)
Lochlainn was originally the name of a land in Irish legend, then it was applied to the homeland of the Norsemen. The first name Loughlin may spring originally from MacLochlainn, 'son of the Scandinavian'. It became widespread in Ireland. Lochlainn was a variant in Irish. Laughlin, a variant in English, was also used to translate Leachlainn, a short form of Maeleachlainn ('servant of St Secundinus'). There is a similar Scottish name, Lachlan, probably 'heroic', 'warriorlike', from Gaelic laoch.
