The Irish name O'Caherney has a long Gaelic heritage to its credit. Generally, the original Gaelic form of the name O'Caherney is said to be Ó Cearnaigh, from the word "cearnach," which means "victorious." 1 However, in some instances, especially the roots of the present day spelling of Kearney, the surname derives from the Gaelic name "Ó Catharnaigh," meaning "warlike."

Early Origins of the O'Caherney family

The surname O'Caherney was first found in County Mayo (Irish: Maigh Eo) located on the West coast of the Republic of Ireland in the province of Connacht, where they held a family seat from ancient times and were a branch of the Ui Fiachrach.

The MacCarney (McCarney) variant is "Mac Cearnaigh and the family was originally seated at Ballymacarney, Co. Meath. According to records from the sixteenth century to the present day it must be regarded as belonging to Ulster: in the Fiants we find a MacCarney among the followers of Rory O'Donnell; in the Hearth Money Rolls of the l660's the name appears frequently in Cos. Monaghan and Armagh; and comparatively recent sources indicate that they are still mainly located in that part of Ulster. It would appear, however, that the prefix Mac has been widely dropped, the name being now registered as Carney or Kearney. Probably the most remarkable person of this name was Susan MacKarney who died in Dublin in 1751 reputedly 120 years of age. She was a beggarwoman who had £250 secreted in the mattress of her death bed." 2

Migration of the O'Caherney family

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 O'Caherney or a variant listed above, including: William Carney who settled in Virginia in 1650; Timothy Carney settled in Virginia in 1751; Easter Carney settled in Virginia in 1752; Mary Carney settled in Pennsylvania in 1773.



The O'Caherney 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: Sustine et abstine
Motto Translation: Sustain and abstain.
