The generation of a Unifying Ancestry for Western Europeans is beneficial for archivists (providing a familial index for persons mentioned in records), historians (providing a familial index between persons involved in historical events), and genealogists (providing a metric for completeness). Complete genealogies will have three main sections: immediate ancestors; connection from the immediate ancestors to the Unifying Ancestry; and connections from the Unifying Ancestry to an Age of Progenitors.
