Facts

Facts are a combination of events and attributes, such as physical description and ethnicity. Facts may have a date, a place, and a value. Some facts may exist multiple times, while others are restricted to just one. The table at the end of this document lists the supported fact types and the different rules which apply to them.

When a fact only supports one conclusion, any attempts to create a second conclusion of the same type will be treated as an update to the existing value. For example, if we tried to create a person with two birth facts, the second birth fact would be treated as an update to the first.

Custom fact types can be created using the data URI scheme as specified by RFC 2397. Examples:

  • data:,Job
  • data:,Military%20Award

The following table lists the supported fact types and the different attributes which they support. Notice that FamilySearch only supports a subset of GEDCOM X conclusion types as well as a few FamilySearch specific types.
