History
The
Historia Brittonum provides the earliest mention of Gwrtheyrnion. According to the text, Vortigern fled to the Gwrtheyrnion after Saint
Germanus of AuxerreGermanus of Auxerre was a bishop of Auxerre in Gaul. He is a saint in both the Roman Catholic and Orthodox churches, commemorated on July 31. He visited Britain in around 429 and the records of this visit provide valuable information on the state of post-Roman British society...

. Additionally, one of the text's copyists, from whose copy most other surviving manuscripts are derived, took particular interest in this kingdom, and introduced a passage on a certain Ffernfael, whose descent is traced back to Vortigern through Pascent. This Ffernfael is also known from the

floruit for Ffernfael around that time.

, were for some time considered part of the
Kingdom of Powys, though in the later Middle Ages Powys exerted no control over them. The
Historia genealogy is interesting in showing that the kings of Gwrtheyrnion themselves claimed no connection to the Powys dynasties, but instead traced their pedigree to the unrelated Vortigern. By the time of Gerald of Wales the general area was known as
Rhwng Gwy a HafrenRhwng Gwy a Hafren was a region of medieval Wales, located in the Welsh Marches between Powys to the north and Brycheiniog to the south.
