The Irish surname McNerney is an anglicized form of the Gaelic name Mac an Airchinnigh meaning “son of the overseer (of church lands),” Gaelic airchinneach, often anglicized as erenagh. The surname arose in different places, notably Munster in the south and Roscommon in the west. As late as the 17th century the 'Mac Inerney' clan was a considerable power. Originally centred on the barony of Bunratty, with the main estate at Ballycally, they opposed the forces of 'The Pale', and suffered grievously as a result. The name first arrived in the New World in the early 1800’s and today there are approximately 2,500 bearers of the name McNerney living in the United States.
