13. Following Kane's return from Europe, we discover that he will soon be married. His soon-to-be wife, Emily, is no less than the niece of the President of the United States. What is her family name?
From Quiz Citizen Kane (Part 3)
Answer:
Norton
Miss Emily Monroe Norton, niece of the current president, becomes Kane's first wife. Their marriage is initially a happy one, but they lose interest in each other, as depicted in the famous breakfast table scene later in the film. In the Newsreel at the beginning of the film it states that, not long after their divorce, Emily and her son (with Kane) are killed in a car accident.
