The Supremes
Founding members Florence Ballard, Mary Wilson, Diana Ross, and Betty McGlown, all came from a public housing project in Detroit. They formed the Primettes as the sister act to the Primes (with Paul Williams and Eddie Kendricks, who went on to form the Temptations). Barbara Martin replaced McGlown in 1960, and the group signed with Motown the following year as the Supremes. Martin left the act in early 1962, and Ross, Ballard, and Wilson carried on as a trio.
