O'Hara is an Irish surname, derived from the original Irish form Ó hEaghra, which means "descendant of Eaghra." The personal name Eaghra is of uncertain origin, but it is supposedly the name of the 10th-century ancestor of the O'Hara family: Eaghra, a 9th- or 10th-century lord of Luighne (an ancient territory in what is now County Sligo and County Leitrim). According to tradition, the O'Hara clan descends from this Eaghra and were for centuries prominent in Connacht, particularly as chiefs of Luighne.
Etymology
The surname is an Anglicization of the Irish Gaelic Ó hEaghra, which uses the prefix Ó meaning "grandson" or "descendant." The spelling O'Hara, with the aspiration represented by the h after the prefix, became the standard form once families adopted the anglicised version. A variant form, O'Harra, exists but is far less common.
Notable Bearers
One of the most famous fictional bearers of this surname is Scarlett O'Hara, the headstrong protagonist of Margaret Mitchell's 1936 novel Gone With the Wind and its 1939 film adaptation. Through this character, the name gained widespread recognition beyond Ireland, though historically the O'Haras were a prominent Irish Gaelic clan.
Cultural Significance
As with many Irish surnames beginning with Ó or O', the name O'Hara reflects a patronymic tradition that dominated Irish naming forms. It places the bearers into a lineage descended from a named ancestor, and such names often retain their distinctive prefix even outside Ireland.
