Notes: The name Moncreiffe comes from the feudal barony of Moncreiffe in Perthshire. The lands of Moncreiffe take their name from the Monadh croibhe which is Scottish Gaelic for Hill of the sacred bough. The plant badge of the clan is the oak and this presumably comes from the sacred tree. Moncreiffe Hill dominates the south-east Perth valley and was a stronghold of the Pictish kings. This connects the clan with the lands of Atholl and Dundas, both of which were held by branches of the Picto-Scottish royal house.
