Benjamin Franklin's beliefs about state & church might have been somewhat influenced by his maternal grandfather, Peter Folger. Folger was one of the founding members of the original community on Nantucket Island. He was brought into the deal to act as translator between the colonists & the indigenous population. The island gave refuge to Quakerism during the time of religious persecution by much of the rest of the Congregational (Puritan) colony of Massachusetts.
Robert Treat Paine's grandfather, Samuel Treat was a Reverend, most likely Congregational.
