According to some accounts the Looneys are said to be of Scotch origin, more often they are considered to befrom Ireland where the O'Looneys were chiefs of Montir Loney, a district known as the Monter Loney Mountains in the county of Tyrone. It is also a Munster surname found chiefly in Cork and Clare, Ireland. Variants of the name are O'Looney; O'Lowney; Lowney; O'Luinie, Lonney, Lunney, Luna, etc.
The Looneys descended from Robert Looney of Augusta and Botetourt Counties, Virginia, and said to have come from Ballagilley Farm about 3 miles south of Ramsey in Maughold Parish, Isle of Man; or possibly from Ballalooney in Amogary Parish. They claim that an ancestor fought with marlborough in Flanders (ca 1708-1709) in the reign of Queen Anne.
