Family tree of Welsh monarchs

This is the family tree of the kings of the respective Welsh medieval kingdoms of Gwynedd, Deheubarth and Powys, and some of their more prominent relatives and heirs as the direct male line descendants of Cunedda Wledig of Gwynedd (401 – 1283), and Gwrtheyrn of Powys (c. 5th century – 1160), then also the separate Welsh kingdoms and petty kingdoms, and then eventually Powys Fadog until the 15th century and also the family of the Tudors of Penmynydd.[1][2][3][4] However, the early generations of these genealogies are traditional, and their historical accuracy is debated by scholars.
