Fintan
The Earldom of Fintan is located in the Duchy of Travlum in the southwestern portion of Gwynedd. The lands are first bestowed upon Sir Martial de Fintan by King Festil I Furstán in 825 to reward the support Martial has provided the king during the first three years of his reign. Originally formed as a barony, the estate is elevated to an earldom by King Cinhil I Haldane in 905. The title reverts back to the Crown after the death of Earl Pliny de Fintan at the Battle of Argoed in 983.
