Members of O'Hara clan include archbishops, writers, and movie stars. Do you have O'Haras in your life? Here's their history.

Variants: Ó hEaghra

Hailing from County Sligo, O’Hara’s are descendants of Eaghra, once Lord of Luighne (an ancient territory in the province of Connacht) and member of the household of Ollum, King of Munster. Eaghra died in 976, but O’Hara clan remained an important sept, and held their ranks as Lords of Luighne (today called Leyney) until the 17th century, and held lands in Sligo up until as recent as the 19th century.

By 14th century, the clan had divided into two distinct septs, led by two chiefs known as O’Hara Buide (yellow, or fair, presumably referring to his hair) and O’Hara Reagh (rough-faced) and center of septs were held at the village of Ballyharry (from ‘Ballyhara’). As landlords, O’Haras held over 20,000 acres (8,000 hectares) of land in Sligo, and at one time a branch migrated north to County Antrim, where there were numerous marriages between O’Haras and great families of the area. Descendants could be found there in later years under name O’Haran or Haren. Today, most O’Haras are still found in Sligo and Leitrim.
