O'Hara Genealogy & History
O'Hara family history holds that the family is descended from Gaelic royalty. Eaghra, from the household of Ollum and ruler of Munster, is considered the progenitor of the O'Haras, even though the name was not recorded before the tenth century. The O'Hara clan finds its origin in County Sligo. This clan experienced a fissure in the 14th century, leaving half of the clan in Colloney and the other in Ballybarry. O'Hara genealogy includes soldier and Michigan Representative James Grant O'Hara; British General Charles O'Hara, who surrendered both to George Washington and Napoleon Bonaparte; and poet and Confederate Colonel Theodore O'Hara.
