Emmeline B. Wells (1828-1921) was General Relief Society President of the Mormon Church, editor of the "Women's Exponent," and an advocate of women's suffrage in the 19th and 20th centuries in Utah.

Helen Mar Whitney (1828-1896) was a Mormon pioneer and plural wife of Joseph Smith.

Helen Mar Whitney was born on August 20, 1828 to Heber C. and Vilate Kimball, in Mendon, New York. Helen's parents joined the Church of Jesus Christ of Latter-day Saints in 1832 and moved to Kirtland, Ohio the following year. Helen's father, Heber, was called to be a member of the Quorum of the Twelve Apostles, a governing body of the church in 1835 and overtime became one of the most prominant leaders of the church. Helen was baptized a member of the church in 1837. The next year the family moved to Far West, Missouri, only to be forced out of the state the year after that. The family then settled in what would become Nauvoo, Illinois.

In 1843 Helen's father arranged for her to marry to Joseph Smith Jr. as a plural wife. After Smith's death in 1844, Helen married Horace Whitney in 1846. Later that year, Helen left Nauvoo with the majority of the Latter-day Saints and spent nearly two years in Winter Quarters, Nebraska. In 1848 she and her family left for the Salt Lake Valley where she spent the rest of her life.

In her later years, Helen was known mostly for her experiences with polygamy, which she frequently recounted in lectures, pamphlets, and articles. Hellen and Horace Whitney had eleven children together, though only six lived to adulthood. Her most prominant child was Orson F. Whitney, a noted author in the Mormon community who was called to be an apostle in 1906. Helen Mar Whitney died on November 13, 1896.
