I will guarantee he will not be named John. There hasn’t been a King John or a John in the line of succession since Magna Carta.
You never know. Who would have guessed the new Pope would be called Francis. No Pope had ever been called that before and no new name had been introduced into the papal ranks since the 900s.
King John had a bad rap. He p*ssed off the Church which meant the only people who could write. He actually had a pretty good run. Stabilized things, etc. I forget and I haven’t had my coffee.
