It was unusual for medieval women to kill their fathers, and especially unusual for them to use crossbows to do it. Juliane de Fontrevault tried both, but she missed King Henry I, who was at the time besieging her castle in Normandy. There had been an altercation, you see, which led to a major hostage failure, wherein Juliane's husband Eustace blinded the young hostage sent to Henry, and Henry blinded and cut the noses off the two girls sent to him as hostages. Who were his grandchildren, by the way. Eventually Henry forgave both Juliane and Eustace; Eustace got to keep a castle and Juliane got to go to Fontevrault Abbey, which was at that time all shiny and new, and her daughters got to go with her. So! It all turned out really well! A happy family story. You're welcome.
