[Apostle John A. Widtsoe reviews the origins of plural marriage; he reviews the evidence that the practice began with Joseph Smith; he identifies Fanny Alger as Joseph Smith's first plural wife; he reviews the testimonies left by "number of men, who in their lives proved themselves honest, [and who] have testified that they actually performed ceremonies that united Joseph Smith to plural wives"; he also cites the testimonies given by Joseph Smith's surviving plural wives and names other Nauvoo-era polygamists; he also mentions Joseph Smith's practice of polyandry.]
