Authorities

The FamilySearch Authorities resource is a collection of Web services that allow genealogical applications to access the name, date, place, and culture authorities used by FamilySearch.

You can use these services to:

• Standardize dates and places like FamilySearch products.
• Segment names and list name variants for each segment.

Standardizing names, dates, and places helps make matching and searching data in FamilySearch more accurate.
