Francine York was born in the small mining town of Aurora, Minnesota to her parents, Frank and Sophie Yerich. When Francine was five, her family (including her younger sister, Deanne) moved to Cleveland, where she began to write short stories and take an interest in acting. At age nine, Francine made her theatrical debut in the Hodge Grammar School production of Cinderella, playing Griselda. Initially quite upset that she did not get the starring role, Francine ended up stealing the show with her performance as the evil stepsister. Right after the show, Francine ran into the audience and told her mother that she wanted to be an actress. When Francine was age 12, the family moved back to Aurora, where she continued to perform in class plays, as well as writing, producing, directing and starring in a three-act play called "Keen Teens or Campus Quarantine". Francine, displaying an entrepreneurial spirit at a young age, charged five cents admission to the show, and the whole town turned out for the production. While studying journalism and drama at Aurora High School, Francine worked as the feature editor of the school newspaper, Aurora Borealis, and she won all of the school's declamation contests with her dramatic readings. Additionally, she was the baton-twirling majorette for the school band, and active in the 4-H club, where she won several blue ribbons for cooking in both county and state fairs. This proved to be valuable experience for Francine later on, when she would not only host, but do all of the gourmet cooking for dinner parties for some of Hollywood's biggest names. At age 17, Francine won the Miss Eveleth contest (Eveleth being a nearby town), and became a runner-up in the Miss Minnesota contest, which was hosted by former Miss America BeBe Shopp. For the talent portion of the Miss Minnesota pageant, Francine, who was not afraid to be less than glamorous during a performance, donned some old clothes, removed her makeup, grayed her hair, and performed a reading of a monologue called "The Day That Was That Day" by Amy Lowell, in which she played a dual role of two elderly Southern women. BeBe Shopp encouraged Francine in her theatrical ambitions, and predicted that she would end up in Hollywood very soon. At this point, however, Hollywood was still a dream for Francine, who wanted desperately to leave Minnesota and make her mark in show business. Moving to Minneapolis, she got a job modeling sweaters for New York-based Jane Richards Sportswear and began traveling throughout the United States, ending up in San Francisco. After leaving Jane Richards, Francine began a modeling course at the House of Charm agency, which started her off on a very successful modeling career for all of the major department stores, including Macy's. Her modeling work got the attention of the producers of the Miss San Francisco beauty pageant, which she subsequently entered and was voted runner-up, but ended up taking over the title after the winner became too sick to participate. Soon after, Francine got a job as a showgirl at Bimbo's, a well-known San Francisco nightclub, which was highly disapproved of by Francine's modeling agency, but this turned out to be the right choice for Francine when she met Bimbo's headliner, singer Mary Meade French, who brought Francine to Hollywood and, later, got her signed with her first agent. Arriving in Los Angeles, Francine once again found herself working as a showgirl at Frank Sennes' Moulin Rouge, a popular nightclub on Sunset Boulevard in Hollywood, where she performed in three shows a night, seven nights a week for six months. Tired of sharing a stage with elephants, pigeons and horses, she moved on to pursue her acting career and began study with famed actor/teacher Jeff Corey. While performing in Corey's class, Francine was spotted by a theatrical producer, who cast her in a play called "Whisper in God's Ear" at the Circle Theatre. During this time, the same producer gave Francine her very first movie role, starring in Secret File: Hollywood (1962), a film about the day-to-day operations of a sleazy Hollywood tabloid.
