Born on April 7, 1943, in Monterey Park, California, Roberta Jymme Schourup quickly gave way to the name Roberta Shore, at a young age, as an actress and singer on film and TV. Raised in San Gabriel, California, Roberta began her career at age ten, singing country western songs at supermarket openings with Tex Williams, who invited her to join his weekly TV show from Knotts Berry Farm. This is when she changed her stage name to "Jymme Shore". She subsequently joined The Pinky Lee Show (1950), NBC's number one rated children's daily television program at the time.
