Sesquipadelian's list "Popes and Antipopes" of 5 great name ideas: Waldrada - Zosimus!

Popes and Antipopes

Just interesting names Popes have had (whether given or chosen), as well as names related to the Popes. Not gonna include the obvious like Peter or John or John-Paul. While many early popes kept their given name, it was often latinized (similarly to how we call Christopher Columbus Christopher even though his first name was likely Cristoffa).
