The Cowsills is an American singing group from Newport, Rhode Island. They specialized in harmonies and the ability to sing and play music at an early age. The band was formed in the spring of 1965 by brothers Bill, Bob, and Barry; they shortly thereafter added John. Originally Bill and Bob played guitar and Barry was on drums. When John learned how to play drums and joined the band, Barry went to bass. After their initial success, the brothers were joined by their siblings Susan and Paul and their mother Barbara. Bob's twin brother Richard was the road manager. When the group expanded to its full family membership by 1967, the six siblings ranged in age from 8 to 19. Joined by their mother Barbara (née Russell), the Cowsills were the inspiration for the 1970 launch of the television show The Partridge Family.
