Daphne Burns (Daphne Martha Charles) 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. It was revealed in the episode 'Homer the Smithers' that she is 122 years old.
Daphne Burns was born Daphne Charles in Springfield. Her father was named Giuseppe Charles and he was the son of Italian and German immigrants (although Burns claims he is neither Italian nor Mexican). Her mother was his illegal Mexican immigrant cleaning women Rosalia Gutierrez. When Daphne was 9, her mother was sent back to Mexico and Daphne never saw her again. Daphne gave birth to her son Charles Montgomery Burns when she was 18.
Now 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".[2] 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.[3] It is possible that he is actually refering 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. In Fraudcast News it is revealed that Daphne Burns is now deceased, her death was caused by the lack of indoor plumbing.
