When 'Mac' (son) occurs in Scottish surnames it
usually signifies a Gaelic origin. This name in Gaelic is Mac a'
Bhriuthainn, meaning ' son of the Judge.' This name is of Scottish descent
and is found in many ancient manuscripts in the above country. Examples of

their rulers, they created charters of ownership for themselves and their
vassals. Other examples of this name were found in the persons of Duncan and
Archibald MacBrayan who were both noted 'rebels' in Argyllshire in the year
