There have been 266 prior popes (give or take an anti-Pope) so in approximately 2,000 years you'd think there'd been a previous Pope named Francis. I mean there have been 8 Urbans, 5 Sixtus's (Sixti?), and 4 Sergius's (Sergiui?).
But apparently that name has been reserved for saints, crooners, scrambling QBs, guys who need to lighten up, and sterile pack animals.
