The name Dunbor comes from the Boernician Scottish-English border region. The Dunbor family lived in the barony of Dunbar on the North Sea coast near Edinburgh. The place name comes from the Gaelic words dùn, meaning "a fort," and barr, meaning "top," or "summit."

Early Origins of the Dunbor family

The surname Dunbor was first found in the barony of Dunbar in the Lothians where they held a family seat from very ancient times; ever since the 11th century, when Cospatrick was deprived of his Earldom of Northumberland by William the Conqueror, and fled to Scotland.

There he was granted the lands of Dunbar and Lothian, Cumnock in Ayrshire, and Mochrum in Wigtown by Malcolm Ceanmore, the King of Scotland. Traditionally, the family descend from Crinan of Dunkeld, the Earl of Northumberland, ancestor of both King Duncan I (d. 1040) and the Earls Gospatrick, who were the later the Earls of March.

Of this line, Patrick V, Earl of March (c.1285-1369) gave English King Edward II sanctuary at the fortress of Dunbar Castle following the Battle of Bannockburn. He was one of the Scottish nobles, who signed, the declaration of Scottish independence to the Pope dated at Arbroath on 6 April 1320.

He was married to the infamous "Black Agnes," Agnes Dunbar, 4th Countess of Moray (1312-1369), "that brawling boisterous Scottish wench" as an English balladeer had called her. In the Earl's absence, she held Dunbar castle for several months before succumbing to the overwhelming English army in 1337. 1

Migration of the Dunbor family

Many of the Boernician-Scottish families who crossed the Atlantic settled along the eastern seaboard in communities that would become the backbone of the emerging nations of the United States and Canada. In the War of Independence, American families that remained loyal to the Crown moved north into Canada and became known as United Empire Loyalists. The ancestral culture of all of these proud Scottish families remains alive in North America in the 20th century through Clan societies and highland games. Early North American immigration records have revealed a number of people bearing the name Dunbor or a variant listed above: William Dunbarr, who arrived in St. Christopher in 1635; William Dunbar, who settled in Virginia in 1650; Alexander Dunbarr, who settled in Virginia in 1654.



The Dunbor 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: In promptu
Motto Translation: In readiness.
