The Descendants of William the Conqueror

A collective long-term work, whose aim is to list all the descendants of William I, king of England, whose lineage has not died out.

Nine out of ten European are descendants of Charlemagne, probably a little fewer are descendants of William the Conqueror! This purely statistical statement is confirmed every day by introducing new lists of descendants of various social backgrounds.
