В английских книгах такие вещи часто встречаются. А в английской Википедии по слову миссис - разъясняется его правильное употребление:

Mrs was most often used by a woman when married, in conjunction with her husband's first and last names (e.g., Mrs John Smith). A widow was and still is addressed with the same title as when she was married. Mrs was rarely used before a woman's first name, her maiden name, or a hyphenated surname her husband was not using. For example, Mrs Jane Smith, Mrs Miller (wife of John Smith), or Mrs Miller-Smith were considered incorrect by many etiquette writers, especially of the early 20th century.
