Sorry about the confusion; there's enough without me added to it.

From an article on Emma Hale Smith:

"The suspension of the Relief Society in 1844, only two years after its organization, was later attributed by John Taylor to Emma's opposition to plural marriage or polygyny (more commonly, polygamy) and concern over her use of the society to preach against it ("Minutes of the General Meeting," [of the Retrenchment Association], July 17, 1880, reported in the Woman's Exponent 9 [Sept. 1, 1880]:53-54). The practice had been privately disclosed as a Church principle in 1840, and Emma's ambivalence enabled her husband to act on her brief acceptance of the doctrine long enough to take additional wives. But her rejection of the principle soon became paramount. Loyal to her husband for seventeen years through all the vicissitudes that his mission had entailed, Emma Smith was unable, at the end, to make the sacrifice that the doctrine of plural marriage required. She struggled between her faith in her husband's prophetic role and her aversion to a principle that he, as Prophet, had been instructed to institute.

After Joseph's martyrdom in June 1844, Emma unfortunately became a symbol of the dissension within the Church. Unable to condone continuation of the practice of plural marriage or the leadership of Brigham Young, who supported it, and ambivalent about the proper line of succession to her husband, Emma made her first priority after her husband's death the preservation of an inheritance for her five living children. Distinguishing Joseph's personal property from that of the Church defied easy solution, however, and involved Brigham Young and Emma Smith in a series of complex and often bitter legal entanglements. Brigham Young, as president of the Quorum of the Twelve Apostles and steward of the Church, claimed all that he felt rightfully belonged to its members. Emma Smith, as guardian of Joseph's children, just as vigorously claimed their share, to which she had contributed throughout her marriage to Joseph. Unable to reach an amicable solution and unwilling to accept plural marriage even in principle, Emma elected to remain in Nauvoo with her family while Brigham Young led the majority of Church members to the Rocky Mountains in 1846. On December 23, 1847, Emma Smith married Lewis Bidamon, a non-Mormon, further estranging her from the Church, to which she had once been known as the Elect Lady. Bidamon assisted Emma in raising her five children and remained her companion until her death in 1879 in Nauvoo.

In 1860, Emma's eldest son, Joseph Smith III, after four years of refusal, accepted the invitation to serve as prophet and first president of the Reorganized Church of Jesus Christ of Latter Day Saints. It was offered by a group of men who formerly had been members of the Church, many of whom had left to follow James J. Strang for a time. As a group they chose not to go west with the body of the Church. Emma, who had heretofore rejected connection with any of the splinter Mormon groups, was admitted into membership in 1860. In his acceptance speech, Joseph III firmly rejected polygamy as a practice of the new church, and Emma denied that her husband had participated in the practice."
