The group that would become the Marvelettes formed at Inkster High School in Inkster, Michigan, a suburb located west of Detroit, Michigan by fifteen-year-old glee club member Gladys Horton in the fall of 1960. Horton enlisted older glee club members Katherine Anderson, Georgeanna Tillman, Juanita Cowart, and a high school graduate Georgia Dobbins (May 5, 1942 – September 18, 2020) to join her. The members struggled to come up with a name for their new act until one of the members jokingly took a stab at their own singing abilities, saying "we can't sing yet." Horton altered the saying to "The Casinyets".
