Ben Franklin was not a Quaker. http://www.adherents.com/people/pf/Benjamin_Franklin.html
may not be authoritative, but being a well-read Friend, I am sure Franklin was not one. He is not claimed as one and Friends had the habit of meticulous record keeping.
There are few Quakers who are household names in American history. The foremost would be William Penn, Rufus Jones, Herbert Hoover, and Richard Nixon.
It is not Friends' practice to devil worship, but mistakes happen. I'll appreciate it, if you won't incite the persecutions to begin again. :-)
