Wikidata:WikiProject Genealogy

Help:FAQ/Genealogy

WikiProject Parenthood maintains a list of family relationship properties.

Records in such databases are usually linked to each other.

See also Wikidata:WikiProject Genealogy/Notables for further examples of these properties.

These databases hold primary information about birth, death, burial, and do not mainly provide family relationship. Sometimes relative information may be found in unlinked texts.

The participants listed below can be notified using the following template in discussions:
