I know the Pope selects his own Papal name when elected, but one of the potential candidates is called Peter...
"Born in western Ghana in October 1948 to a Methodist mother and a Catholic father, Peter Turkson became the first-ever Ghanaian cardinal in 2003 when he was appointed by Pope John Paul II.
The 64-year-old is the relator, or general secretary, of the Synod for Africa, making him a strong candidate to become the first African pope of the modern age, taking on a mantle that was held during the 2005 Conclave by Nigerian Cardinal Francis Arinze.
The last two Popes both served as relators for a synod of bishops."
