Today's Irish surnames are underpinned by a multitude of rich histories. The name Cawnor originally appeared in Gaelic as Ó Conchobhair, derived from the personal name Conchobhar. 1

Early Origins of the Cawnor family

The surname Cawnor was first found in Connacht. There were six different septs of this famous name scattered throughout Ireland, of which four continue to boast many members. However, the most important O'Connors were those of Connacht, divided into three main branches: O'Conor Don; O'Conor Roe; and O'Conor Sligo.

The Connacht O'Connors were direct descendants of Conchobhar, King of Connacht, who died in 971 AD. Furthermore, this family produced the last two High Kings of Ireland: Turlough O'Connor (1088-1156) and Roderick O'Connor (1116-1196). It was the invasion of Leinster by Roderick O'Conner on behalf of the Prince of West Brefney that caused the King of Leinster, Dermod MacMorough, to flee to England for aid. This resulted in the Strongbow Invasion of 1168, the beginning of English domination over Ireland.

Despite remaining stubbornly Catholic, the O'Connor family continued to maintain their elite position among the Irish nobility throughout the entire period of British dominance.

Migration of the Cawnor family

A great mass of Ireland's native population left the island in the 19th century, seeking relief from various forms of social, religious, and economic discrimination. This Irish exodus was primarily to North America. If the migrants survived the long ocean journey, many unfortunately would find more discrimination in the colonies of British North America and the fledgling United States of America. These newly arrived Irish were, however, wanted as a cheap source of labor for the many large agricultural and industrial projects that were essential to the development of what would become two of the wealthiest nations in the western world. Early immigration and passenger lists indicate many people bearing the Cawnor name: William Conner who settled in Plymouth, arriving on the "Fortune" in 1621; just a year after the "Mayflower," Cornelious Conner, who settled in Exeter in 1650.



The Cawnor 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: O Dhia gach an cabhair
Motto Translation: From God Every Help
