McInerney

Etymology

McInerney is an Anglicized Irish surname built on Mac/Mc, meaning “son” or “descendant of,” plus a Gaelic personal name or byname recorded in older forms such as Macinerney. The second element is not entirely secure in the older scholarship, so the precise literal meaning remains uncertain. In practice, the surname is treated as a hereditary family name of Gaelic Irish origin rather than a descriptive English word.

History

The name is associated especially with County Clare in Ireland and appears in Irish historical records in medieval and later forms. Like many Gaelic surnames, it was preserved through Anglicization with varying spellings, but McInerney became the standard modern form. The 19th-century sources supplied here mention it only in passing, supporting its recognition as a distinct Irish surname rather than explaining its derivation.
