Born in New York City in 1934, Carol Kelly was out of a performing family that also included sister Nancy Kelly and brother Jack Kelly, both of whom enjoyed long screen and television careers. Carol, though, not so much and her only prominent assignment came in Terror in a Texas Town 1958), a low budget but quite interesting western starring Sterling Hayden, directed by cult phenomenon Joseph H. Lewis and penned by actor Nedrick Young. The later, who was blacklisted, was unbilled.
Carol married prolific actor Joe Marross in 1958 but divorced him four years later. In her complaint, she alleged that her husband beat her and once even pulled her around the house by her ankles. "I guess I just can't adjust to marriage," Marross had explained in lieu of an apology. Carol was awarded full custody of their son, Michael.
