History of the Saints presents the story of Mary Fielding Smith. From her birth and upbringing in rural England, through her conversion and gathering with the Saints, to her marriage to Hyrum Smith and subsequent grief at his martyrdom. The story culminates in her unusual struggle to cross the plains and establish her own independence on a small farm in East Millcreek in the Salt Lake Valley. Mary saw herself as merely doing her duty. Today, we see her as so much more.
