Show ContentsDeasey History, Family Crest & Coats of Arms

The Deasey family saga is rooted in the people of the Pictish Clan of ancient Scotland. The Deasey family lived in Angus (in the modern region of Tayside), and claim descent from Gaelic MacDhai, son of David. 1

Early Origins of the Deasey family

The surname Deasey was first found in Angus (Gaelic: Aonghas), part of the Tayside region of northeastern Scotland, and present day Council Area of Angus, formerly known as Forfar or Forfarshire, where they were descended from the Gaelic MacDhai, son of David. From the 13th century onward the name was anglicized MacDavid, Davidson, Deasson and Deas. The branches using Deas and Deasson settled in Angus and in Banffshire at the end of the fifteenth century.

"James Dais is recorded in Dundee, 1611, and Mr. John Daes in Huntliewood, 1638. James Daes was minister of the church of Ersiltoune, 1643. Andrew Daes, stabler, appears in Edinburgh, 1627, and David Daes, tailor there, 1666." 2

United States Deasey migration to the United States +

The freedom of the North American colonies was enticing, and many Scots left to make the great crossing. It was a long and hard journey, but its reward was a place where there was more land than people and tolerance was far easier to come by. Many of these people came together to fight for a new nation in the American War of Independence, while others remained loyal to the old order as United Empire Loyalists. The ancestors of Scots in North America have recovered much of this heritage in the 20th century through Clan societies and other such organizations. A search of immigration and passenger lists revealed many important and early immigrants to North America bearing the name of Deasey:
