Born in Indianapolis, Indiana to Marion Edmund Ensley and Wilna Eunice Ensley née Coyner, Walton came from a lively, educated, Quaker family. Walton suffered chronic respiratory illnesses as a child, and was privately or self-taught at home. Her parents separated and divorced in 1924. Growing up and living with her mother and her grandmother and witnessing her parents’ marital difficulties roused a natural feminism in Walton which appears throughout her writings. As a child, Walton enjoyed the works of L. Frank Baum, James Stephens, Lord Dunsany and Algernon Blackwood, which she would later cite as influences on her fiction. Walton and her mother traveled often to New York City, Chicago and San Francisco for opera, especially for Richard Wagner’s Der Ring des Nibelungen; opera was a passion her entire life. In 1946 after the death of her grandmother, Walton and her mother moved to Tucson, Arizona. Wilna Ensley died in 1971 but not before she saw the dawn of public recognition for Walton and her works.
