"Paul McCartney is widely celebrated as the English rock star and bass guitarist who co-wrote much of the Beatles' hit songs alongside John Lennon."
A surname, from Irish​., notably of Sir Paul McCartney (b. 1942), one of the Beatles
"John Lennon and George Harrison joined forces with his friend Peter to form a new group known as The Quarrymen before becoming part of the legendary band featuring McCartney."
The surname McCartney is an Anglicized version of the Scottish Gaelic Mac Artaine, which literally means "son of Artan." Because Artan was a diminutive form of the name Art, the ultimate root traces back to Old Irish art, meaning "bear."
