Mac Bethad of Rosemarkie

Mac Bethad (fl. 1127 x 1131) is the first recorded High Medieval Bishop of Ross, a See then located at Rosemarkie.

He makes his only historical appearance as Macbeth Rosmarkensis Episcopus (i.e. "Mac Bethad, Bishop of Rosemarkie") in a list of witnesses to a charter granted by King David I of Scotland to the Church of Dunfermline, confirming the previous rights of that church.^[1]

The charter is dated by its modern editor to 1128,^[2] but is more safely dated to the period between the years 1127 and 1131.^[3]
