This project evaluates the concept of a Unifying Ancestry, to which all persons of Western European Descent should be able to link their ancestors.  The basis for a core genealogy is the set of common ancestors of the royal lines of Europe (34,067 persons).  To test the concept, 616 persons identified in Palmer's History of the Modern World have been linked to the genealogy, comprising 84% of the total number mentioned in the history book.  A paper on "Trustworthy Communications and Complete Genealogies: Unifying Ancestries for a Genealogical History of the Modern World" is available at https://www.coregen.center and on Amazon.  The Research Genealogy and Coregen3 Analysis Workbench are available as free educational software from both the Mac App Store and Microsoft Store.
