Emily Partridge (February 28, 1824 - 1899) ended up nannying for the Smiths after her father, Edward Partridge, bishop of Nauvoo, died in 1840. A year in Joseph asked Emily if she would be willing to read a secret letter and then burn it. She wouldn't.
Not long after that Elizabeth Durfee stepped in and had a sit down with Emily and her sister Eliza. The topic? Plural marriage.
Joseph approached Emily again on her nineteenth birthday, this time with words she couldn't decline to hear. Days later Elizabeth approached Emily again and send her to meet Joseph at Heber Kimball's home. It was a plot to get Joseph married to her right then and there. Heber's two children were sent to the neighbor's house and Emily was to leave with them, only she was immediately called back with loud whispers. She found herself alone with Joseph and Heber. Joseph explained that God had given her to him. She decided it best to go along with things and marry Joseph. The newly weds didn't consummate their marriage that night, but did sleep together on various occasions afterward.
This, people, sounds like an abduction, not a holy covenant. It resembles abuse, not love.
As usual the marriage took place without Emma's knowledge or permission. Joseph then used the temple endowment oath of wifely obedience to her husband to leverage Emma into accepting plural marriage. Emma was endowed only after accepting the Partridge sisters as sister wives and standing witness to a second farcical wedding.
Denounce your husband and lose your crown? I think not!
After Joseph's assassination Emily married Brigham Young, with whom she had seven children.
