Kimball, I think your points are well made, and not trivial. We have used the PGM template for anyone in the migration years, so perhaps it would bring clarity to drop Puritan from the template name.
Many of the immigrants I have researched were indeed devout Puritans, and organized themselves into tight villages around a church, making a point of keeping out anyone who did not agree with their principles.
On the other, some of the people I've looked up were quite obviously motivated by the opportunity for land and wealth, and very pointedly disagreed with the Puritan doctrine.
A case in point, William Pynchon, who founded Roxbury in 1630, founded Springfield in 1636, and although he was definnitly religious, he was so in conflict with the Puritan authorities of Massachusetts that when he published The Meritorious Price of Christ's Redemption in 1650, it became the first banned book in America and led to him fleeing back to England to avoid suffering the same fate as his book - burned in public.
