Married to fellow African American James Gist who she filmed Hell Bound Train with, among other amateur films. According to the Women Film Pioneers project, Gist was a co-director, co-producer, screenwriter and film editor. Eloyce was of the Bahá’í faith while her husband was a Christian evangelical. The couple had a goal of producing entertaining films with strong moral and spiritual mission. Both worked together to find audiences in the African American community and churches, ran low budgets with non-professional actors and made 16mm films to accompany religious services. Tepperman (2014) notes that all their films featured religious parables, featured all-black casts and some films were sponsored by the National Association for the Advancement of Colored People (NAACP).
