For the most American holiday, steeped in tradition, a new book on "The Mayflower: The Families, The Voyage and The Founding of America." British historian Rebecca Fraser focuses on Edward Winslow, who she calls the most important, but least remembered, of the group of separatists known as the Pilgrims. We discuss the challenges they faced in England and in the New World, as well as the role of women and their changing relationship with the Native Americans.
