History of the Hanrahan name

Ó hAnracháin is generally derived from anradh, a warrior or champion. The sept originated in County Clare and spread through Limerick, Tipperary and Kilkenny, where the name is still most at home; a Cork branch of the same stock is usually anglicised Hourihane. Yeats borrowed the name for his wandering poet Red Hanrahan, giving it a permanent place in Irish literature. In real life the name became a byword for tenacity when John Hanrahan, a Tipperary farmer, took on the pharmaceutical giant Merck over toxic emissions harming his herd and won a landmark Supreme Court victory in 1988, one of Ireland's most important environmental cases.
