According to Wikipedia, there were a number of tiny kingdoms that were ruled separately and later joined together as Deheubarth.  I will have to do some research in order to find the actual line of blood that might be our relatives.
Also, there were rulers of Powys farther north.  Not only did they marry into the Deheubarth line, but I believe that they may have some relationship to the Owen family, our relatives connecting later into this family.

The Deheubarth area contains a small penninsula in the far south that contains the oldest known burial in the British Isles, 29,000 years old, known as the Red Lady of Paviland.  It was also the traditional home of two pre Roman British Celtic tribes known as the Silures and the Demelae
