In the October 2015 issue of The Journal of Mormon History, Gary Bergera presents a richly illustrated article, "Memory as Evidence: Dating Joseph Smith's Plural Marriages to Louisa Beaman, Zina Jacobs, and Presendia Buell" (95–131). It focuses on a page from the "Historian's Private Journal," which Bergera dates to "specifically September or thereabouts" of 1866 (99). Wilford Woodruff's handwriting on that page describes Joseph Smith's plural marriage sealings and dates his marriage to Louisa Beaman to "May 1840," to Zina Huntington on "October 27, 1840," to Presendia Huntington on "December 11, 1840," and also to Rhoda Richards on "June 12, 1843." The first three dates on the historian's document are important, as Bergera explains: "If accurate, Woodruff's record not only pushes back the beginnings of Joseph Smith earliest Nauvoo plural marriage by a year but it also requires that we reevaluate what we think we know -- and how we know it -- about the beginnings of LDS polygamy" (95–96). The key question is whether the information on that page can be considered "accurate" in light of other available documents dealing with these plural sealings. During the remaining thirty-four pages of the article, Bergera presents an argument that 1840, not 1841, is the most reliable year for the Prophet's earliest Nauvoo plural unions. This essay examines why his analysis of the records appears to be incomplete and his conclusions problematic.
