More than 185,000 Utah families were identified on "Family Group Sheets" from the archives at the Utah Family History Library. These sheets contain demographic and kinship information on three generations. For a family to be selected for the Utah Population Database (UPDB), at least one member had to have a vital event (birth, marriage, or death) on the Mormon Pioneer Trail or in Utah. These families have been linked across generations. These records are different from those available on the Web through FamilySearch or other publicly available genealogical databases and have been maintained as a resource only for biomedical researchers. The Genealogy File includes the following:
- Migrants to Utah and their Utah descendants
- About 1.6 million individuals born from the early 1800s to the mid-1900s
- Birth and death information that occurs in any state or country
- Linked multi-generation pedigrees
The Ancestral File is used to add genealogies or update genealogies, as needed. It is a collection of pedigree charts and family group records on CD ROMs. It contains about 14 million names; however, information on living individuals is restricted. These records are not linked to other data sets and are not available on the network. They are available to use in the UPDB offices at Huntsman Cancer Institute.
