Mary Dyer’s story has been difficult to tell because the surviving records are sparse: there are long periods where she is lost from sight, and there is much that remains unknown about her. Nevertheless, this biography uncovers new material about Dyer, her husband, and their associates from a variety of little explored or previously unexplored sources.

It’s been a long haul and I am profoundly grateful for the many folks who have offered encouragement, support, and insight along the way. Special thanks to Jeremy Brecher, Beth Powning, David Hall, Larry Ingle, Francis Bremer, and the second, anonymous reader for the former university press. Mary Dyer was hanged in Boston in 1660 for civil disobedience and her husband held important offices in early Rhode Island.
