O-caddint History, Family Crest & Coats of Arms
- Origins Available:
The surname O-caddint 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 O-caddint family
The surname O-caddint was first found in Leinster, where they were descended from Bran, the King of Leinster who died in 1052.  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." 
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).

Migration of the O-caddint family
Thousands of Irish families left for North American shores in the 19th century. These people were searching for a life unencumbered with poverty, hunger, and racial discrimination. Many arrived to eventually find such conditions, but many others simply did not arrive: victims of the diseased, overcrowded ships in which they traveled to the New World. Those who lived to see North American shores were instrumental in the development of the growing nations of Canada and the United States. A thorough examination of passenger and immigration lists has disclosed evidence of many early immigrants of the name O-caddint: Dinnis Byrne, who settled in Barbados in 1679; Adam O'Byrne, who settled in Jamaica in 1734; James and Patrick O'Byrne, who arrived in Philadelphia in 1806.

The O-caddint 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.
