I have already read most of the FARMS Review of George D. Smith's Book Titled, 'Nauvoo Polygamy: ". . . but we called it celestial marriage,"' Reviewed by Gregory L. Smith. Here is an interesting Paragraph from that Review:
"There is no reason to doubt," G. D. Smith tells us, "that [Joseph's] marriages involved sexual relations in most instances" (p. 227). There is, in fact, relatively little evidence with which to judge, which means that some doubt is prudent. There is good evidence of a conjugal relationship with Almira Johnson, Melissa Lott, Emily Partridge, and Eliza R. Snow. It is also reasonable to include Eliza Partridge, Maria Lawrence, and Sarah Lawrence. The evidence for their inclusion is persuasive, though they are not named specifically. There is late, hostile evidence of intimacy with Fanny Alger, and most intriguingly there is some evidence of both a physical relationship and a child with Sylvia Sessions Lyon.[185] This is only nine marriages out of Todd Compton's list of thirty-three—or G. D. Smith's list of thirty-eight—plural marriages.
And Here is Footnote # 185:
[185] G. D. Smith ignores Brian C. Hales, "The Joseph Smith–Sylvia Sessions Plural Sealing: Polyandry or Polygyny?" Mormon Historical Studies 9/1 (Spring 2008): 41–57, which argues that Sylvia considered herself divorced prior to marrying Joseph polygamously, contrary to evidence misread by Compton. There is no evidence for sexuality in any other polyandrous marriage. I have outlined my reasons for believing that there are no other viable candidates for potential polygamous children (save Josephine Lyon) in Gregory L. Smith, "Children from Joseph's Plural Marriages?" draft chapter in The Principle: A history of LDS plural marriage (2007); available online at http://en.fairmormon.org/Joseph_Smith_a ... ok_chapter (accessed 2 December 2008).
This is the first time that I read, that Sylvia Sessions Lyon considered herself divorced from her husband Windsor Lyon when she Polygamously married Joseph Smith. I do definitely believe that Josephine Rosetta Lyon (Fisher) was indeed the biological daughter of Joseph Smith.
