I thought it was seven generations. I know that I have genealogical connections to the King of France who sentenced the Knights Templers and he was cursed so my son refers to it as the pizza curse because he can never get the pizza he orders by phone. It got watered down after the first seven generations.
Lucky you. When Philip LeBel (King of France as you know) sentenced the head of the Templars to die at the stake, from the flames the Templar cursed him as well as the Papal representative and said "I will see you before God's throne within the year"
In fact, both died within the year.
