Kierney
The Earldom of Kierney is located in northwestern Gwynedd, situated on the western shore of the Gulf of Kheldour. The Duchy of Cassan lies to the north, the Earldoms of Culdi and Transha to the south, and lands of Meara to the west. Once a part of the sovereign Principality of Cassan, it is conquered by King Festil I Furstán in 822 and bestowed upon Lord Iolo MacLean, one of the king's close companions. The title passes to the House of MacInnis in 918, and eventually to the House of McLain a century later. In the late eleventh century, Kierney becomes a secondary title of the Dukes of Cassan, often being bestowed upon the duke's heir. In 1130, the sixteenth Earl of Kierney is Duke Dhugal MacArdry McLain, who also holds the titles of Duke of Cassan and Earl of Transha.
