In 1869, Ann Eliza Young married Brigham Young, becoming what she believed to be his nineteenth wife. She went on to file for divorce in 1873, alleging neglect, cruel treatment, and desertion. She was excommunicated from the church in 1874, and the divorce was granted the following year. She would go on to lead a fight against polygamy, Mormonism, and Brigham Young, testifying before US Congress.
