The group performed in benefits and high school parties before being signed to the Chess Records subsidiary Checkmate (later bought by Motown Records), where the group recorded a single, "I'll Let You Know", with Williams on lead. Once at Motown, the group during this period sung backing vocals for other acts/artists on studio recordings, such as Marvin Gaye. Williams sung lead on an early single, "There He Is (At My Door)", on the Mel-O-Dy subsidiary of Motown after the group changed their name to The Vels. On the single's flip side, "You'll Never Cherish A Love So True", she shares the lead with Reeves (who recorded her first lead on this song).
However, when the single flopped, a frustrated Williams left the group leaving the band as a trio. The group went on to international fame with Reeves as lead singer under the name of Martha and the Vandellas.
Williams died of diabetes complications in Detroit on July 5, 2000. She was 57 years old.
