Martha Burns (Daphne Charles on the family tree in The Simpsons Uncensored Family Album) is Charles Montgomery Burns's mother. She was married to Clifford Burns. She once had an affair with President Taft; Mr. Burns never forgave her. As revealed in the episode "Homer the Smithers", she is 122 years old.
Present EditNow all she is capable of doing is dialing phone numbers and yelling. It is also referenced that Mr. Burns killed her and her husband when he says that his parents’ cause of death was "Got in my way". However, he implied that he may have attempted to "pull the plug" on her as revenge for her extramarital affair with William Taft, but had not expected her to live another five decades, when Homer attempted to pretend to be his mother as part of a scheme to get Smithers rehired (after Homer unintentionally disconnected his mother from the phone while attempting to transfer the call to his line). When Burns almost dies, he also asks if the voice he hears is his mother, which could mean that she has died. After buying out KBBL and firing Bill and Marty, Mr. Burns comments that the lack of indoor plumbing killed his mother. It is possible that he is actually referring to his grandmother Evelyn Graycomb, who is technically his adoptive mother, much like how he sometimes refers to his grandfather Wainwright Montgomery Burns as his father, as he was forcibly adopted by him during his childhood.
