O’Hara ~ Ó hEaghra

The Story of the O’Hara Name

O’Hara is the anglicized form of the Irish Ó hEaghra, meaning “descendant of Eaghra.” Eaghra was an ancient Gaelic lord of Luighne, a territory in what is now County Sligo. The O’Haras became one of the important Gaelic families of Connacht, maintaining their connection to the region for many centuries.

The O’Haras were traditionally the lords of Luighne, now known as the barony of Leyney in County Sligo. Their ancestral lands lay in the heart of western Connacht, where the family established itself as a powerful Gaelic dynasty. By the fourteenth century, the family had divided into two principal branches, known as O’Hara Buidhe and O’Hara Riabhach, reflecting distinctive descriptions associated with their respective chiefs.

The O’Haras maintained their position in County Sligo through centuries of political change, although their fortunes declined as English authority expanded across Ireland. A branch of the family also moved north into County Antrim, where the name became established in the Glens. The original O’Hara territory in Sligo was eventually lost during the upheavals of the seventeenth century, bringing an end to much of the family’s traditional political power.

Behind the familiar name O’Hara lies the story of an ancient Connacht dynasty rooted in the landscape of County Sligo. From the historic territory of Luighne, Ó hEaghra became O’Hara, preserving the memory of a family that once ruled as lords of Leyney and whose name remains deeply woven into the history of western Ireland.
