Question: What is the full name of the character married to a gay antique dealer?  Answer the above question based on the context below:  In Visitors from New York, Hannah Warren is a Manhattan workaholic who flies to Los Angeles to retrieve her teenaged daughter Jenny (played by Dana Plato) after she leaves home to live with her successful screenwriter father Bill. The bickering divorced couple is forced to decide what living arrangements are best for the girl. In Visitors from London, Diana Barrie is a British actress and a first-time nominee for the Academy Award for Best Actress in an independent British film, an honour that could jumpstart her faltering career, although she knows she doesn't have a chance of winning. She is in deep denial about the true nature of her marriage of convenience to Sidney Cochran, a once-closeted gay antique dealer who has become increasingly indiscreet about his sexuality. As she prepares for her moment in the spotlight, her mood fluctuates from hope to panic to despair. In Visitors from Philadelphia, conservative middle-aged businessman Marvin Michaels awakens to discover a prostitute named Bunny - an unexpected gift from his brother Harry - unconscious in his bed. With his wife Millie (Elaine May) on her way up to the suite, he must find a way to conceal all traces of his uncharacteristic indiscretion. In Visitors from Chicago, Dr. Chauncey Gump and his wife Lola and Dr. Willis Panama and his wife Bettina are taking a much-needed vacation together. Things begin to unravel quickly when everything seems to go wrong and the two men decide to settle their differences by engaging in a very competitive mixed doubles tennis match.
