This week, we’re going from the almost-historically-grounded arms attributed to Llywelyn ap Gruffudd to the absolutely spurious arms attributed to Rhys ap Tewdwr and the House of Dinefwr. It is a pretty common attribution, but given that the power of Dinefwr and their realms of Deheubarth had faded considerably by the time heraldry started to gain traction in Wales, I’m somewhat skeptical that these arms have any basis in historical fact.
Anyway. Given that Rhys ap Tewdwr died in literally the eleventh century, we don’t have a whole lot of information about him. He was descended from Rhodri the Great via Cadell ap Rhodri and Hywel Dda. His last wife, Gwladys ferch Rhiwallon of Powys, had a daughter named Nest, whose descendants include the families of FitzGerald and de Barry. Unfortunately, Rhys’ death led to the breakup of his lands, with his heir Gruffydd ending up with some, and the Normans ending up with a whole lot more.
