The Documented Descent

Notable Ancestors and Cousins

The documented descent records a network of notable kin. Direct ancestors trace generation-by-generation to medieval kings and the Holy Roman Empire. Documented cousins extend laterally to figures across English royalty, American statecraft, and reform movements. Each connection below is rendered in full on its dedicated proof page.
