About
Gruffudd Fychan, hereditary prince of Powys Fadog and lord of Glyndyfrdwy and Sycharth, died about 1369, leaving a son the world would come to know: Owain Glyndwr, the last native Prince of Wales, took from this quiet border lord his descent from the old royal house of Powys. That descent now stands wired in this tree, ten rungs from Gruffudd to Bleddyn ap Cynfyn, king of Powys and Gwynedd, who died in 1075.
