McCleary is an Anglicized form of the Irish surname Mac Cléirich, which in turn comes from the Gaelic Mac Cléirigh meaning "son of the clerk" or "son of the priest." The name originated in Galway, Ireland, but today it is primarily found in Ulster and Scotland, with many descendants among Ulster Scots and Irish communities in North America.
Etymology
The Gaelic root Mac Cléirich (Mac Cléirigh) literally means "son of the cleric." This occupational byname refers to a cleric or priest, indicating that the original bearer was either a clergyman or worked in one of the religious roles common in medieval Ireland. Variants of the name include Cleary, Clery, and MacClery, as well as the Irish form Ó Cléirigh. Cognates in other languages include Dutch surnames such as De Clerc, De Clercq, and De Klerk, all deriving from the same occupational root.
The earliest possible bearer of the name is Mael Fabhaill mac Cleireach, an ancestor of the Ó hEidhin/Hynes family of County Galway, who flourished around 800 AD. Over time, surnames like Clarke and MacTaggart also developed from similar meanings ("cleric" or "priest"), reflecting the importance of religious roles in early Irish society. Orphans were often taken in by religious orders, and priests (before clerical celibacy became standard) sometimes fathered children, which may have contributed to the spread of this surname type.
