The lives of missionary wives in pioneer Utah were often filled with financial difficulty, childhood illness, and social isolation. Church leaders intended these struggles to be a holy sacrifice, but the lived reality was rarely thought of as religious devotion. Additionally, many women constantly worried that their husbands would marry other wives. Despite their critical role in populating the 19th-century American West, few records of their experiences survive. In this interview, Jennifer Lund and Elizabeth Oberdick Anderson highlight the rare letters of Sarah “Sanie” Peterson Lund, a Scandinavian immigrant whose weekly correspondence to her missionary husband has been preserved.
