Thousands of Scots left their home country to travel to Ireland or Australia, or to cross the Atlantic for the North American colonies. The difficult crossing was an enormous hurdle, but those who survived found freedom and opportunity in ample measure. Some Scots even fought for their freedom in the American War of Independence. This century, their ancestors have become aware of the illustrious history of the Scots in North America and at home through Clan societies and other organizations.

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: Quid non pro patria Motto Translation: What would not one do for his country.
