'Muireadhach I.' (also written as ''Murethach'', ''Murdoch'' or ''Maurice'') is the second known
Mormaer of
Menteith. He succeeded his father
Gille CrÃst 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.
Muireadhach Mór's right to the Mormaerdom was challenged at some stage by his younger brother, also called Muireadhach, hence
Muireadhach Óg (in
English, "the younger"). The case apparently went to arbitration, and the king decided on the right of Muireadhch Óg. On
December 13,
1213, Muireadhach Mór resigned the Mormaerdom, taking lesser lands and titles in compensation. It is not known for how long Muireadhach Mór lived, nor is it known if he had any wives or offspring.
