The International Genealogical Index (IGI) is a database of genealogical records, compiled from several sources, and maintained by the Church of Jesus Christ of Latter-day Saints. Originally created in 1969, the index was intended to help track the performance of temple ordinances for the deceased.
The IGI contains free genealogical information, submitted from various sources including names and data for vicarious ordinances by Latter-day Saints (LDS) researchers, records obtained from contributors who are not members of the church, and data extracted from microfilmed birth or marriage records. The index contains millions of records of individuals who lived between 1500 and 1900, primarily in the United States, Canada, Latin America, and Europe. Ongoing efforts are made to compile genealogical data from other regions and peoples.
The IGI contains many duplicate names, accumulated over time from many sources, and no real effort is made to validate the information. Many IGI records contain information on the submitter and date of submission (but only with the submitter's consent). The IGI is available at FamilySearch, the LDS genealogy website.

Genealogy is the study of families, family history, and the tracing of their lineages. Genealogists use oral interviews, historical records, genetic analysis, and other records to obtain information about a family and to demonstrate kinship and pedigrees of its members. The results are often displayed in charts or written as narratives. The field of family history is broader than genealogy, and covers not just lineage but also family and community history and biography.
Mormonism is the theology and religious tradition of the Latter Day Saint movement of Restorationist Christianity started by Joseph Smith in Western New York in the 1820s and 1830s. As a label, Mormonism has been applied to various aspects of the Latter Day Saint movement, although since 2018 there has been a push from The Church of Jesus Christ of Latter-Day Saints to distance themselves from this label. A historian, Sydney E. Ahlstrom, wrote in 1982 that, depending on the context, the term Mormonism could refer to “a sect, a mystery cult, a new religion, a church, a people, a nation, or an American subculture; indeed, at different times and places it is all of these."

A parish register, alternatively known as a parochial register, is a handwritten volume, normally kept in the parish church of an ecclesiastical parish in which certain details of religious ceremonies marking major events such as baptisms, marriages, and burials are recorded.

These records exist in England because they were required by law and for the purpose of preventing bigamy and consanguineous marriage.
