This is some information you could use. Roger williams and William Penn were both colonists from Europe. Williams governed RI and Penn governed PN. Rhode Island had true religious freedom unlike any other colony. The Religious group called the Quakers lived in Pennsylvania. That was about the only religion there. They were both New England colonies. I hope you can make something from that!
A conversation that William and roger would have is one that involved advocating for religious toleration for religious reasons since they both had this in them. They both shared the fact that people should not judge each other when it comes to matters of faith but rather leave it to ones' consciousness.
