Feidhlimidh O'Donnell
Feidhlimidh O'Donnell was a son of Aodh O'Donnell and the eleventh O'Donnell chief. When Aonghus died in 1352, Feidhlimidh seized the kingship of Tyrconnell, but his nephew Seán contested it for years.
In 1355 his heir Donnchadh was killed at the court of the Maguire king of Fermanagh while trying to abduct his host's daughter. In 1356 Seán killed him and took the lordship unopposed.
