In Wharfinger’s The Courier’s Tragedy, Francesca is a noblewoman who is connected through incest to both the houses of Squamuglia and Faggio. She is Angelo’s sister and lover, but she was also the former lover of the Duke of Faggio, who is the father of her son Pasquale. Before the events of the play, Angelo killed the Duke of Faggio and replaced him with Pasquale instead of his legitimate heir, Niccolò. Then, he insists that Francesca marry her son Pasquale in order to unite the two duchies. Francesca objects, but Angelo insists that Francesca cannot complain about sleeping with her son if she is already sleeping with her brother. In some versions of the play, she does marry Pasquale, while other versions include a disturbing sex scene between her and Angelo.
