The ancient Dalriadan clans of Scotland spawned the name McDiarmid. It is derived from the personal name Dermid which is derived from the Gaelic Mac Dhiarmaid, which means son of Dermid. "The Macdiarmids of Glenlyon claim or claimed to be the oldest if not the aboriginal race of the district. Nemeas Mactarmayt was rector of St Conganus de Duybrinis (Durinish) and afterwards vicar of Kilchoman in Islay, 1427. " 1

United States McDiarmid migration to the United States +

Many settled along the east coast of what would become the United States and Canada. As the American War of Independence broke out, those who remained loyal to the crown went north to Canada as United Empire Loyalists. The ancestors of all of these hardy Dalriadan-Scottish settlers began to recover their collective history in the 20th century with the advent of the vibrant culture fostered by highland games and Clan societies in North America. Highland games, clan societies, and other organizations generated much renewed interest in Scottish heritage in the 20th century. The McDiarmid were among the earliest of the Scottish settlers as immigration passenger lists have shown:

The McDiarmid 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: Non immenor beneficii
Motto Translation: Grateful for kindness.
