Robinson was probably born in Cincinnati, Ohio, but no records of her birth are known. When she was ten years old, she found work touring with a white act, the Four Dancing Mitchells. As a teenager, she danced in Salem Tutt Whitneys Smart Set. In 1913, she left the Tutt Brothers to sing in clubs in Harlem and married William Smitty Smith, a singer.
