On 6 April 1830, the “Church of Christ” was legally organized in Fayette, New York with the first six members being Joseph Smith, Jr., Oliver Cowdery, Hyrum Smith, Peter Whitmer, Jr., Samuel H. Smith and David Whitmer. Later names for this organization included the Church of the Latter Day Saints, the Church of Jesus Christ, the Church of God, the Church of Christ of Latter Day Saints and (in 1838), the Church of Jesus Christ of Latter Day Saints. Over the ensuing decades, more than 90,000 people joined churches associated with the Latter Day Saint movement. During the lifetime of Joseph Smith, the main body of the church was headquartered at different times in New York, Ohio, Missouri and Illinois. After Joseph Smith Junior’s death in 1844, members of descendant organizations of the church established by Joseph Smith settled in Iowa, Nebraska, the Intermountain West, Wisconsin, Pennsylvania, and other areas. Nevertheless, congregations of Latter Day Saint churches were also established in other parts of the world and the scope of this project includes individuals who joined Latter Day Saint movement churches during this same timeframe anywhere in the world (including Europe, Oceania, South Africa, and other parts of North America), but who may not have resided in the main areas where these churches were established.
