FamilySearch

FamilySearch is a nonprofit organization and website offering genealogical records, education, and software. It is operated by the Church of Jesus Christ of Latter-day Saints and is part of the Church's Family History Department (FHD). The Family History Department was originally established in 1894, as the Genealogical Society of Utah (GSU); it is the largest genealogy organization in the world.

FamilySearch maintains a collection of records, resources, and services designed to help people learn more about their family history. Facilitating the performance of Latter-day Saint ordinances for deceased relatives is another major aim of the organization. Although it requires user account registration, it offers free access to its resources and service online at FamilySearch.org. In addition, FamilySearch offers personal assistance at more than 6,400 FamilySearch centers in 140 countries, including the FamilySearch Library in Salt Lake City, Utah. The Family Tree section allows user-generated content to be contributed to the genealogical database. As of March 2023, there are over 1.5 billion individuals in the tree and the historical records database contains over 5.7 billion digital images, including digitized books, digitized microfilm, and other digital records.
