Allen, Allan, Alianach—MAC AILEAN.—The latter name is a form assumed by a branch of the McAllens, a McFarlane sept in the North of Scotland. The Allens of Co Kerry and other parts of Munster are descendants of a Scottish sept of the McAllens who came to Tirconnell from the West of Scotland in the 15th century to serve as Gallowglasses under the O'Donnells. In a battle in 1558 with the forces of the Earl of Clanrickard they were defeated and dispersed, one branch settling in Co. Kerry. This sept be longed to the clan Campbell.
