The surname Byrns was "O Broin," in its Gaelic form, which means descendant of Bran. The family is descended from Bran, the king of Leinster who died in 1052, who, along with King Conn of the Hundred Battles descended from Cathair Mor, an earlier king of Leinster, who was also monarch of all Ireland around 200 AD.

Early Origins of the Byrns family

The surname Byrns was first found in Leinster, where they were descended from Bran, the King of Leinster who died in 1052. 1 He was descended from Cathair Mor King of Leinster, who was also Monarch of all Ireland about 200 A.D. From this stem King Conn of the Hundred Battles was also descended. During the Strongbow invasion in 1172, the family, along with the O'Tooles, were driven from their original lands in county Kildare, settling the wilder territory between Rathdrum and Shillelagh, in south Wicklow.

"The O'Bymes anciently possessed the greater part of the Barony of Ballinacor, County Wicklow, and wore powerful Chiefs in that part of the country. Byrne is the leading name now in the Counties of Wicklow, Dublin, and Louth." 2

The sept increased in importance, and like their similarly displaced neighbors, were especially noted for their lengthy and tenacious resistance to the English invaders. Their successes in this struggle were numerous. Their military exploits of this time are celebrated in a compilation by some thirty-five authors of Gaelic poetry called the Leabhar Branch (Book of the O'Byrnes).1

United States Byrns migration to the United States +

To escape the religious and political discrimination they experienced primarily at the hands of the English, thousands of Irish left their homeland in the 19th century. These migrants typically settled in communities throughout the East Coast of North America, but also joined the wagon trains moving out to the Midwest. Ironically, when the American War of Independence began, many Irish settlers took the side of England, and at the war's conclusion moved north to Canada. These United Empire Loyalists, were granted land along the St. Lawrence River and the Niagara Peninsula. Other Irish immigrants settled in Newfoundland, the Ottawa Valley, New Brunswick and Nova Scotia. The greatest influx of Irish immigrants, however, came to North America during the Great Potato Famine of the late 1840s. Thousands left Ireland at this time for North America and Australia. Many of those numbers, however, did not live through the long sea passage. These Irish settlers to North America were immediately put to work building railroads, coal mines, bridges, and canals. Irish settlers made an inestimable contribution to the building of the New World. Early North American immigration records have revealed a number of people bearing the Irish name Byrns or a variant listed above, including:

The Byrns 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: Certavi et vici
Motto Translation: I have fought and conquered.
