(March 17, 1947 - August 5, 1955) (her death)
Desiring creative freedom, Miranda decided to produce her own film in 1947 and played opposite Groucho Marx in Copacabana. The film's budget was divided into about ten investors' shares. A Texan investor who owned one of the shares sent his brother, David Sebastian, to keep an eye on Miranda and his interests on the set. Sebastian befriended her, and they began dating.
Miranda and Sebastian married on 17 March 1947 at the Church of the Good Shepherd in Beverly Hills, with Patrick J. Concannon officiating. In 1948 Miranda became pregnant, but miscarried after a show. Although the marriage was brief, Miranda (who was Catholic) did not want a divorce. Her sister, Aurora, said in the documentary Bananas is My Business: "He married her for selfish reasons; she got very sick after she married and lived with a lot of depression". The couple announced their separation in September 1949, but reconciled several months later.
