Hundreds of years ago, the Gaelic name used by the O'Dunne family in Ireland was Ó Duinn or Ó Doinn. Both Gaelic names are derived from the Gaelic word donn, which means brown. Ó Doinn is the genitive case of donn. 1

Early Origins of the O'Dunne family

The surname O'Dunne was first found in County Meath (Irish: An Mhí) anciently part of the kingdom of Brega, located in Eastern Ireland, in the province of Leinster. The family was descended from O'Rigain one of the ancient "Four Tribes of Tara" in the Kingdom of Meath, now the county of Meath. The Kings of Meath in turn traced their regal history back to the Heremon Kings.

Migration of the O'Dunne 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 O'Dunne name: Thomas Dunn who settled in Wymouth, Massachusetts in 1647; Miss Dunn settled in Barbados in 1774; Mrs. Dunn settled in Boston Massachusetts in 1766; Agnes Dunn settled in Charles Town [Charleston], South Carolina in 1767.

The O'Dunne 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: Mullach a-bu
Motto Translation: Victory for the Dunns.
