The surname "Kelleher" is of Irish origin. It is derived from the Gaelic name "Ó Céileachair," which means "descendant of Céileachar." The Gaelic name itself is believed to be composed of two elements: "céile," meaning "companion" or "associate," and "car," which can mean "loving" or "friend." The Kelleher surname is predominantly found in County Cork, Ireland, and is associated with the ancient clan or sept of O'Kelleher. The O'Kellehers were an important family in the region and held positions of influence and authority. Over time, the prefix "Ó" was often dropped, and the surname became Kelleher.
