June 1842 - Joseph Smith (Age: 36) married Elizabeth Davis Durfee (Age: 51), who at the time was married to Jabez Durfee.
"When Elizabeth met Jabez Durfee in 1834 she was a widow, having lost her first two husbands in a shipwreck and sickness. Jabez was a widower, his wife having passed away earlier that year. They combined their families, 10 children between them, and were married in March of 1834 in Clay County, Missouri." (In Sacred Loneliness: The Plural Wives of Joseph Smith pg 259)
"Elizabeth and Jabez moved to Nauvoo in 1839. There, Elizabeth participated in the newly established women’s organization, the Relief Society. On April 14, 1842 Elizabeth was administered to by Society President Emma Smith and her two counselors. Later Elizabeth, “bore testimony to the great blessing she received when administered to...by Prest. E.S. & Councillors Cleveland and Whitney. she said she never realized more benefit thro’ any administration-that she was heal’d, and thought the sisters had more faith than the brethren”. In response to complaints about women giving blessings, Joseph shared his approval saying, “If the sisters should have faith to heal the sick let all hold their tongues...if God gave his sanction by healing...there would be no...sin.”" (Mormon Enigma: Emma Hale Smith pg 110; In Sacred Loneliness: The Plural Wives of Joseph Smith pg 261)
"In the Spring of 1842 Elizabeth, now fifty one, married Joseph Smith. Like Patty Sessions, another one of Joseph’s relatively older wives, Elizabeth was a “Mother in Israel” who helped introduce younger women into plural marriage. In the Spring of 1843, nineteen-year-old Emily Partridge recalls being approached by Joseph: “If you will not betray me, I will tell you something for your benefit...[he] asked me if I would burn it if he would write me a letter”. Emily declined Joseph’s letter thinking, “it was not the proper thing to do”. Soon after, Elizabeth invited Emily to her home. Emily remembers, “She introduced the subject of spiritual wives as they called it in that day [and wondered] if there was any truth in the report she heard...[I thought to myself] I could tell her something that would make her open her eyes if I chose”. Emily kept quiet but later noted, “I learned afterward that Mrs. Durfee was [already] a friend to plurality and knew all about it”. On March 4th, Elizabeth again met with Emily. Emily wrote, “Mrs. Durf- came to me one day and said Joseph would like an opportunity to talk with me. I asked her if she knew what he wanted. She said she thought he wanted me for a wife...I was to meet him in the evening at Mr. Kimballs”. Aided by Elizabeth's prompting, Emily met and married Joseph that evening."

"After Joseph’s death in 1844, Elizabeth separated from her first husband, Jabez, and soon married Cornelius Lott. Lott’s daughter Melissa had also been a wife of Joseph Smith. Elizabeth and Cornelius started west with the majority of the saints. Elizabeth’s son, John remembers, “we went with [Brigham] as far as the Missouri River and then we saw so much of their manner of doing business, that we went back to Quincy”. Cornelius continued on to Utah, eventually taking 5 plural wives. In Quincy, Elizabeth renewed her friendship with “President” Emma Smith."
