Have you ever found an interesting person on Wikipedia and want to know more about that person’s family relationships? It is often possible and is actually quite easy!
Click the “Wikidata item” link on left side of page.
Scroll thru the WikiData page looking for links to sites like FamilySearch, WeRelate, WikiTree, Geni, etc.
Not all persons on Wikidata have links to those sites; but there are many.
Enjoy!
