The last name of the three brothers in The Beach Boys is Wilson. Brian, Dennis, and Carl Wilson were the three brothers who formed the family core of the band.
The group began in Hawthorne, California, in 1961. Brian Wilson organized the early musical arrangements, Dennis Wilson played drums, and Carl Wilson played guitar. Their cousin Mike Love and family friend Al Jardine completed the original lineup. Because Love was a cousin rather than a brother, Wilson is the single surname shared by the band's three brothers.
The brothers had different musical roles and personalities. Brian became the principal composer, producer, and arranger; Dennis was the only genuine surfer among the founding members and served as drummer; and Carl developed into a lead vocalist, guitarist, and later musical leader. Their shared surname is sometimes confused with the names of other prominent members, especially Love, Jardine, and Bruce Johnston.
