List of Famous people named Muireadhach

Muireadach II of Menteith, ruled 1213-1231, was the son of Gille Críst and the third known Mormaer of Menteith. Muireadach gained the Mormaerdom by challenging the rights of the current Mormaer, his elder brother, also called Muireadhach, hence Muireadhch Mór. The case apparently went to arbitration, and the king decided on the right of Muireadhch Óg. On 13 December 1213, Muireadhach Mór resigned the Mormaerdom, taking lesser lands and titles in compensation.

Muireadhach III, Earl of Menteith was a Scottish nobleman.

Muireadhach I is the second known Mormaer of Menteith. He succeeded his father Gille Críst by the time of his appearance in a charter of William the Lion confirming the church at Moulin to Dunfermline Abbey. The charter is undated, but must have been written between 1189 and 1198. He appears again in a charter agreement between Gilbert, Prior of St Andrews, and the local Céli Dé dating sometime after 1198.
