International Genealogical Index (IGI) - FamilySearch Historical Records

What is in This Collection?
Significant changes were made to this collection in December 2020. Please read this section for more information.

The International Genealogical Index (IGI) is a computer file created by The Church of Jesus Christ of Latter-day Saints. It was first published in 1973 and continued to grow through December 2008. It contains several hundred million entries, each recording one event, such as a birth, baptism (christening), marriage, or death.

The original IGI collection on Historical Records was divided into two sections:
 * 1) Indexed Historical Records (Community Indexed IGI) containing approximately 460 million names transcribed directly from source material and submitted to the church. The indexed data that was part of the IGI has been organized into its original source collections from which it was transcribed and it now resides in the Historical Records system.
 * 2) User Contributions (Community Contributed IGI) containing approximately 430 million names submitted to the Church of Jesus Christ for which no historical record collection source is known. Some of these records came directly from original sources. For a short period of time duplication in the IGI was reduced by removing records from the indexed data when these records were submitted by the community, but the original collection annotation was lost. The majority of the records may contain data from multiple sources.

In December 2020 the collection was split so the content from Indexed Historical Records (Community Indexed IGI) would be searchable only through the International Genealogical Index (IGI) Historical Records collections. The User Contributions (Community Contributed IGI) can be searched as part of the collections found on Search Genealogies.

How Do I Search This Collection?
To begin your search it is helpful to know the your ancestor’s name as well as some identifying information such as the date and place of birth or the spouse’s name.

How Do I Analyze the Results?
Compare each result from your search with what you know to determine if there is a match. This may require viewing multiple records or images. Keep track of your research in a research log.

I Found the Person I Was Looking For, What Now?

 * Add any new information to your records
 * Make sure to fully transcribe and cite the record entry for future reference; see below for assistance in citing this collection. Save or print a copy of the image if possible
 * Use the information which has been discovered to find more. For instance, use the age listed in the record to estimate a year of birth, if that is yet undetermined
 * Continue to search the index to identify children, siblings, parents, and other relatives. Note that family members often appear on an individual's vital records, such as in the role of witnesses to a marriage

I Can’t Find the Person I’m Looking For, What Now?

 * When looking for a person with a common name, look at all the entries for the name before deciding which individual is correct. Use other information, such as place of birth, age, occupation, or names of parents, to determine which candidate is the correct person. If listed, a personal title may be a clue to property ownership or occupation, either of which might be noted in other records
 * Check for variants of given names and surnames; simple clerical errors were always possible. In addition, spelling was not standardized for much of the period of this collection, so pay special attention to how the name should have been pronounced and try variations on the pronunciation. Individuals could also be listed under a middle name, or abbreviation of their given name. For women, it was not uncommon to revert to a maiden name after the death of a husband
 * Vary the search terms. For example, search by either the given name or surname to return broader list of possible candidates which can then be examined for matches. Alternatively, try expanding the date range
 * Search the records of nearby locations
 * Look at the actual image of the record to verify the information found in the online description, if possible
