OCinnéidigh

OCinnéidigh is an Irish surname. It is the anglicized form of the Gaelic Ó Cinnéidigh. The name translates to "descendant of Cinnéidigh." The personal name Cinnéidigh itself is derived from "cinn," meaning "head," and "éidigh," meaning "ugly" or "armored." Therefore, the surname can be interpreted as "descendant of the ugly-headed one" or "descendant of the armored head."

The sept of Ó Cinnéidigh was historically prominent in Munster, particularly in the region of Ormond, which encompassed parts of modern-day counties Tipperary and Limerick. They were a notable Gaelic clan, often associated with warfare and leadership. Branches of the family held lands and positions of influence within the region for centuries.

As with many Irish surnames, variations in spelling have emerged over time due to anglicization and phonetic transcription. Common anglicized forms include Kennedy, Kennedie, and Kinneady, with Kennedy being the most prevalent. The surname is widespread today, both in Ireland and among the Irish diaspora, particularly in the United States, Canada, Australia, and the United Kingdom. Notable individuals bearing the surname have made significant contributions in various fields, including politics, sports, and the arts.
