This article analyzes the “conversion” of Anthony Uzodimma Obinna, an Igbo schoolteacher from the town of Aboh Mbaise in Imo State, and his extended family to Mormonism in southeastern Nigeria between the 1960s and the 1980s, from a historical perspective. I argue that the transition of Anthony Obinna and his family away from Catholicism to Mormonism can be explained by both the elective affinities that existed between Mormonism and indigenous Igbo culture, and socio-economic factors as well. This article bases its conclusions on a close reading of oral histories, personal papers, and correspondence housed at the LDS Church History Library in Salt Lake City, Utah and L. Tom Perry Special Collections at Harold B. Lee Library, Brigham Young University in Provo, Utah.
