O'Hearn History, Family Crest & Coats of Arms
- Origins Available:
Many Irish surnames can be traced back to their Gaelic forms. The name O'Hearn originally appeared in Gaelic as O hEachthigheirn or O hEachthigheirna, made up of the words "each" meaning "steed," and "thighearna," meaning "lord." This was first Anglicized O'Hagherin, which was later changed to O'Aherne before the prefix was eventually dropped. 
Early Origins of the O'Hearn family
The surname O'Hearn was first found in County Clare (Irish: An Clár) located on the west coast of Ireland in the province of Munster, where they held a family seat as a Dalcassian sept from before the year 1000. However, with the disruptions of the Strongbow Invasion of 1172, they migrated southward to counties Cork and Waterford. In Waterford the name is predominantly Hearn and Hearne.
