This article, originally a lecture given at Brigham Young University in 2009, was published as part of a special issue of BYU Studies featuring Thomas L. Kane. Although Kane was not a member of The Church of Jesus Christ of Latter-day Saints, he was an advocate for the Mormon cause and a trusted friend of Mormon leaders for almost forty years. Bennion and Carter consider the ideas presented by Elizabeth Kane, Thomas’s wife, who expressed her dismay with plural marriage in her writings about her visit to Utah in 1872–73. The authors combine Elizabeth’s views with their interest in Mormon architecture and historical geography through an examination of one of the homes that Elizabeth portrayed in her book Twelve Mormons Homes. This article aids in current understanding of the everyday lives of Latter-day Saints participating in plural marriage.
