OMainin

OMainin is a surname of Irish origin. It is an anglicized form of the Gaelic O'Maoilfhionn, meaning "descendant of Maoilfhionn". The personal name Maoilfhionn itself is composed of two elements: "maol," meaning "bald" or "chief," and "fionn," meaning "fair" or "white." Thus, OMainin can be interpreted as "descendant of the fair-haired chief" or "descendant of the bald chief."

The OMainin sept was historically located in the region of County Westmeath in Ireland. Over time, as with many Irish surnames, the spelling and pronunciation have evolved. Variations of the name include Mullin, Molloy, and others, though OMainin retains a distinct identity. Individuals bearing the OMainin surname or its derivatives can be found in Ireland and have since dispersed to other parts of the world, particularly in countries with significant Irish diaspora such as the United States, Canada, Australia, and the United Kingdom. Genealogical research often traces the lineage of OMainin families back to their ancestral lands in Westmeath. The name itself carries a rich history tied to Irish clan structures and Gaelic heritage.
