OMaoileachlainn

OMaoileachlainn is an Irish surname. It is an anglicized form of the Gaelic O Maoileachlainn. The prefix O' signifies descent from a grandfather, and the personal name Maoileachlainn is derived from the first name Maol Seachlainn, which is believed to mean "devotee of St. Seachlan" or "bald devotee of Seachlan". St. Seachlan was an early Irish saint. The surname is most commonly found in the province of Munster, particularly in County Clare and County Tipperary. Historically, the O'Maoileachlainn family was prominent in the region of Dealbhna, which is now known as the barony of Delvin in County Westmeath, though the name has since become more associated with Munster. Variations in spelling can occur due to the anglicization process, and include forms like McLaughlin, MacLoughlin, and Malachy. Individuals bearing this surname have contributed to various fields throughout Irish history and in modern times.
