O'Coonor History, Family Crest & Coats of Arms

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

Early Origins of the O'Coonor family

The surname O'Coonor 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 O'Coonor family to the New World and Oceana

Death and immigration greatly reduced Ireland's population in the 19th century. For the native Irish people poverty, hunger, and racial prejudice was common. Therefore, thousands left their homeland to seek opportunity in North America. Those who survived the journey and the quarantine camps to which they arrived, were instrumental towards building the strong developing nations of the United States and the future Canada. By far, the largest influx of Irish settlers occurred with Great Potato Famine during the late 1840s. These were employed as construction or factory workers. An examination of passenger and immigration lists has shown early immigrants bearing the name O'Coonor: 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 O'Coonor 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
