I don't agree with the practice, I personally consider it an error. But at least it's now one that I can legitimately raise from a church source if relevant.Several later documents suggest that several women who were already married to other men were, like Marinda Hyde, married or sealed to Joseph Smith. Available evidence indicates that some of these apparent polygynous/polyandrous marriages took place during the years covered by this journal. At least three of the women reportedly involved in these marriages—Patty Bartlett Sessions, Ruth Vose Sayers, and Sylvia Porter Lyon—are mentioned in the journal, though in contexts very much removed from plural marriage.58 Even fewer sources are extant for these complex relationships than are available for Smith’s marriages to unmarried women, and Smith’s revelations are silent on them. Having surveyed the available sources, historian Richard L. Bushman concludes that these polyandrous marriages—and perhaps other plural marriages of Joseph Smith—were primarily a means of binding other families to his for the spiritual benefit and mutual salvation of all involved.
