At first, she knew nothing of her husband's multiple murder attempts. When she does become aware, she helps Sideshow Bob try to kill the Simpson family. She and Gino, along with Sideshow Bob's mother, father, and brother attempted to have Bart incinerated to get revenge.
Her design may be based on her voice actress, Maria Grazia Cucinotta.
- It is unknown what happened to her or Gino after "Funeral for a Fiend", especially considering that they don't appear again together with Bob to help him in his plans of revenge against Bart Simpson in other episodes. Though that is possibly due to the obsession of Bob wanting to kill Bart, this could eventually cause a strain in their relationship, and Francesca could suggest divorce with Bob off-screen, leaving Sideshow Bob on his own again, and possibly giving him another reason to get revenge against Bart Simpson. In addition, in "Bobby, It's Cold Outside", when asked about children he doesn't mention his son and his wedding ring is apparently nowhere in sight. He even mentioned in a list of "life goals" to date age-appropriate woman, more signs Francesca is gone.
