The surname Byrnes 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 Byrnes family

The surname Byrnes 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 Byrnes migration to the United States +

A massive amount of Ireland's native population left the island in the 19th century for North America and Australia in hopes of finding more opportunities and an escape from discrimination and oppression. A great portion of these migrants arrived on the eastern shores of the North American continent. Although they were generally poor and destitute, and, therefore, again discriminated against, these Irish people were heartily welcomed for the hard labor involved in the construction of railroads, canals, roadways, and buildings. Many others were put to work in the newly established factories or agricultural projects that were so essential to the development of what would become two of the wealthiest nations in the world. The Great Potato Famine during the late 1840s initiated the largest wave of Iris immigration. Early North American immigration and passenger lists have revealed a number of people bearing the name Byrnes or a variant listed above:

The Byrnes 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.
