Clavis GeneticaThe key to genetic genealogy

Further links

The book's list of sources says where every number and every claim comes from. Here are its 62 web addresses, ready to click, in the order of the chapters. The explanations, that is what each source supports and how things were counted, are in the book.

The links lead to external sites whose content I cannot influence. Last checked: 6 October 2026. If an address no longer works, I would be glad of a note.

The book is written in German. Chapter titles, source notes and updates therefore appear in German on this page.
