full_question: This group is represented by a dove in the Book of the Three Birds, written by a Welsh member of this group named Morgan Llwyd (HLOO-id). A member of this religious group adopted the pseudonym "Martin Marprelate" to pen a series of attacks against authorities. A thousand of them presented the king with the Millenary Petition, enabling them to receive a voice at the Hampton Court Conference. The mortal enemy of this religious group was William (*) Laud, the Archbishop of Canterbury. Between 1620 and 1640, large numbers of these people left England for Holland, though many were dissatisfied with their lives there. For 10 points, name these English Protestants who settled in New England, whose name is now synonymous with extreme straight-laced piety.
