On the western coast of Scotland and on the Hebrides islands the McGreagor family was born among the ancient Dalriadan clans. Their name comes from the given name Gregory. The Gaelic form of the name was Mac Griogain, which translates as son of Gregory.

Early Origins of the McGreagor family

The surname McGreagor 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.

The McGreagor 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.
