Not to say you are wrong, but there were few Puritans in those parts, and even in Pennsylvania German was the dominant language ~
Just to remind you English speaking people were just one of a variety of other peoples already here!
Yes on German in some colonies. Some Huguenots even joined the Dutch Reformed Church in the area of what is New York now, and at least a very few of those were Sephardim (after fleeing first from Spain to France and hiding in France for generations before Holland, Jersey, etc., then landing here).
