Joseph Norwood, at Slate, admires the religiously enthusiastic Onomastic customs of Puritan New England.
My personal favorite Puritan name is If Christ Had Not Died For Thy Sins Thou Shouldst Be Damned Forever Barebones.
Even after these kinds of expressive of over-the-top religious sentiments personal names went out of fashion, Puritan New Englanders still continued naming their children, right up into the early 20th Century, in colorful and distinctive ways. I actually used to know a Reverdy Whitlock. But my favorite new era Puritan name, dating from the late 18th century, would have to be Epaphroditus Champion.
