Jean Carroll's lineage was deeply rooted in the entertainment industry, with both her parents being accomplished actors. Her mother, Fern Lacey, held a significant role as the original "Buster Brown" in vaudeville, a testament to her talents.
Jean, along with her sister JoAnn, who was crowned "Miss Hollywood" in 1932, began their careers in Hollywood by taking on extra and bit parts at M.G.M. and Hal Roach Studios from 1931 to 1933. As they honed their skills, they transitioned to vaudeville and eventually became headlining performers in burlesque from 1933 onwards.
The sisters' partnership came to an end in 1936, after which Jean continued her career, working alongside her then-husband Bob Carney and Billie Bird at the prestigious Colony Club in Gardena during the 1950s. During this time, she appeared in various films, as documented in her IMDb filmography, showcasing her versatility and range as a performer.
