I heard Mrs. Betsy Gilett, say in our house in Kirtland before the Prophet Jo Smith left for Missouri, that he practiced a plurality of wives. There was very much talk among the old women about plurality of wives. . . .
Alexander claims that Joseph "had a revelation to lie with Vienna Jaques, who lived with his family" in Kirtland.
Brian Hales argues that this specific "allegation was. . . .unknown until decades after Joseph Smith's death." See Hales, "Fanny Alger and Joseph Smith's Pre-Nauvoo Reputation," Journal of Mormon History 35:4 (2009): 123-127.
