The meaning and origin of the last name Ohara

The surname Ohara has its origins in Ireland, and it is derived from the Gaelic surname Ó hEaghra, which means "descendant of Eaghra." The name Eaghra itself is believed to derive from the Irish word "eagar," meaning "splendid" or "fierce." The Ohara surname is most commonly found in the western parts of Ireland, particularly in County Kerry and County Mayo. Throughout history, the O'Haras were a prominent and influential sept of Gaelic nobility in these regions. They were known for their warrior skills and were often leaders in battle. During the 17th century, Ireland faced the Cromwellian conquest and subsequent Plantation invasions, which caused significant disruption among Gaelic families, including the O'Haras. Many were dispossessed of their lands and forced to relocate or change their surnames to avoid persecution. As a result, some O'Haras may have anglicized their surname, dropping the O' prefix or modifying it to Ohara, O'Hara, or simply Hara. Today, Ohara remains a relatively common surname in Ireland and is also found among Irish diaspora communities worldwide.
