The Picts of ancient Scotland were the tribe of the ancestors of the McOy family. The name McOy is derived from the personal name Aodh, a cognate of Hugh. The Gaelic form of the name is usually Mac Aoidh and in Inverness, the Gaelic form of the name McOy is Mac Ai.

"Nothing certain is known of the origin of the northern Mackays beyond the fact that they were early connected with Moray, and may have been a part of the ancient Clann Morgunn. The Inverness-shire Mackays are usually called in Gaelic Mac Ai, that is, MacDhai, or Davidson; they formed a branch of Clan Chattan." 1

Early Origins of the McOy family

The surname McOy was first found in Sutherland (Gaelic: Cataibh), a former county in northern Scotland, now part of the Council Area of Highland, where early records show that Gilcrest M'Ay, forefather of the MacKay family of Ugadale, made a payment to the constable of Tarbert in 1326. It is claimed that the Clan is descended from the royal house of MacEth.

Migration of the McOy family

The cruelties suffered under the new government forced many to leave their ancient homeland for the freedom of the North American colonies. Those who arrived safely found land, freedom, and opportunity for the taking. These hardy settlers gave their strength and perseverance to the young nations that would become the United States and Canada. Immigration and passenger lists have shown many early immigrants bearing the name McOy: Denis McCoy and his wife Catharine, who were colonists in Amelia county, Virginia in 1719; Agnes, Angus, Alexander, Anna, Catherine, Daniel, George, James, John, Margaret, Neil, Samuel and William McKay, who all arrived in Pennsylvania in 1772.



The McOy 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: Manu forti
Motto Translation: With a strong hand.
