History & Origin

McCoy anglicizes the Irish and Scottish Gaelic surname Mac Aoidh, meaning son of Aodh, where Aodh is an ancient Celtic fire deity name cognate with the Welsh Aedd and ultimately connected to the Proto-Celtic word for fire. The name was common in both Ireland and Scotland, producing separate McCoy and MacKay clans.

McCoy as a given first name is a recent American trend driven by the surname-as-first-name fashion and the cultural resonance of the real McCoy idiom. The Hatfield-McCoy feud of the 1880s in Appalachia also gave the name a rugged American frontier association. The medical character Dr. Leonard McCoy on Star Trek has kept the name in pop-cultural view.

Did you know? The phrase the real McCoy meaning the genuine article has several proposed origins, including Scottish whiskey producer Mackay, American prohibition-era rum runner Bill McCoy who sold genuine liquor, or Canadian inventor Elijah McCoy whose oil-drip cup was so reliable that engineers asked for the real McCoy device. The true origin remains debated.
