Gwerthrynion (Guorthigirniaun)
This tiny principality or region was located to the north of Builth.
It seems to have been
part of Vortigern's ancestral lands, and bears his name in its Welsh form.
Initially part of Vortigern's Powys, it was
governed entirely by Builth and
subject to its rule. Its rulers were the same of those of Builth itself, all
of whom could trace their descent to Vortigern,
but information on the principality is extremely patchy. |
