Show ContentsGregor History, Family Crest & Coats of Arms

The west coast of Scotland and the rocky Hebrides islands are the ancient home of the Gregor family. The root of their name is the given name Gregory. The Gaelic form of the name was Mac Griogain, which translates as son of Gregory.

Early Origins of the Gregor family

The surname Gregor was first found in Argyllshire (Gaelic erra Ghaidheal), the region of western Scotland corresponding roughly with the ancient Kingdom of Dál Riata, in the Strathclyde region of Scotland, now part of the Council Area of Argyll and Bute, as their origins can be traced back to Griogair, son of the eighth century King Alpin of Scotland, the High King of the Scots and Picts who died in 860 AD. Hence, their famous motto translates from Gaelic as 'Royal is my blood.' They are the principal branch of the Siol Alpine whose representative, King Kenneth the Hardy, was son of MacAlpin, the first King of the Scots.

United States Gregor migration to the United States +

Numerous Scottish settlers settled along the east coast of the colonies that would become the United States and Canada. Others traveled to the open country of the west. At the time of the American War of Independence, some remained in the United States, while those who remained loyal to the crown went north to Canada as United Empire Loyalists. The highland games and Clan societies that sprang up across North America in the 20th century have helped many Scots to recover parts of their lost traditions. Research into passenger and immigration lists has revealed some of the very first Gregors to arrive in North America:

The Gregor 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: 'S Rioghal Mo Dhream
Motto Translation: Royal is my blood.
