The name Mhaighstir comes from the ancient Scottish kingdom of Dalriada, where it was used to indicate someone who worked as a cleric. The Middle Gaelic word magisder is borrowed from the Latin magister. The Gaelic form of the surname is Mac a Mhaighstir, which means son of the Master. 1

Early Origins of the Mhaighstir family

The surname Mhaighstir was first found in Ardgour (Scottish Gaelic: Ard Ghobhar, meaning Height of the goats), where they were anciently derived from members of the Clan MacInnes, who changed their name.

"This surname is now found mainly in the shires of Dumfries and Wigtown, but was also the name of a sept in Ardgour traditionally said to have been dispossessed by Macleans in the fifteenth century." 1

Migration of the Mhaighstir family

Descendents of Dalriadan-Scottish families still populate many communities across North America. They are particularly common in Canada, since many went north as United Empire Loyalists at the time of the American War of Independence. Much later, in the late 19th and early 20th centuries, the highland games and Clan societies that now dot North America sprang up, allowing many Scots to recover their lost national heritage. Some of the first immigrants to cross the Atlantic and come to North America bore the name Mhaighstir, or a variant listed above: James McMaster, who sailed to Boston in 1766; Elizabeth MacMaster sailed to New York in 1774; Angus MacMaster migrated from Lochaber, Inverness to Inverness County, Nova Scotia in 1802.



The Mhaighstir Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto: MacAonghais a-rithist
Motto Translation: Again MacInnes
