At first, she knew nothing of her husband's multiple murder attempts. When she does become aware, she helps 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.
Francesca is also the "Finger-Pointing Blame Shifter" type of mom you meet at the PTA.
- 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 helps him in his plans of revenge against Bart Simpson in other episodes. Though that is possibly due to the obsession of Bob wanting to murk 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.
