LAS VEGAS — Mary Wilson, one of the original members of the Supremes, the 1960s group that helped establish the Motown sound and propelled Diana Ross to superstardom, has died. She was 76.
Wilson died Monday night at her home in Nevada and the cause was not immediately clear, said publicist Jay Schwartz.
Wilson, Diana Ross and Florence Ballard made up the first successful configuration of The Supremes, Motown’s first and most commercially successful girl group. Ballard was replaced by Cindy Birdsong in 1967, and Wilson stayed with the group until it was officially disbanded in 1977.
