Name Database:  

Although the information and resources contained in the Family History library of The Church of Jesus Christ of Latter-day Saints are the most extensive and comprehensive of their kind, not all of these resources and information are available online through FamilySearch.

The Ancestral File database is a collection of genealogical information taken from pedigree charts and family group records submitted to the Family History Department since 1978, it contains over 36 million names. The information is not verified against any official records—those who use the Ancestral File contribute the information.

The International Genealogical Index database contains approximately 600 million names of deceased individuals. An addendum to the International Genealogical Index contains an additional 125 million names. These names have been patron submitted or extracted from thousands of original birth, christening and marriage records

The Pedigree Resource File database contains over 80 million names that are linked into families.
