Ambrosius Aurelianus was a war leader of the Romano-British who won an important battle against the Anglo-Saxons in the 5th century, according to Gildas. He also appeared independently in the legends of the Britons, beginning with the 9th-century Historia Brittonum. Eventually he was transformed into the uncle of King Arthur, the brother of Arthur's father Uther Pendragon, as a ruler who precedes and predeceases them both. He also appears as a young prophet who meets the tyrant Vortigern; in this guise, he was later transformed into the wizard Merlin.
Cigfa ferch Gwyn Glohoyw is a minor character in Welsh mythology, the wife of King Pryderi of Dyfed. She is mentioned briefly in the First Branch of the Mabinogi, and appears more prominently in the third. Describing the character, Proinsias Mac Cana writes: "Cigfa strikes one as a slight though effective vignette of a contemporary bourgeois snob while William John Gruffydd hypothesises that the character was a later addition to the tale." John Rhys suggested a connection between Cigfa and the Irish character Ciochba.
Vortigern, also spelled Vortiger, Vortigan, Voertigern and Vortigen, was a 5th-century warlord in Britain, known perhaps as a king of the Britons or at least connoted as such in the writings of Bede. His existence is nonetheless contested by scholars and information about him is obscure.
Paul Aurelian was a 6th-century Welshman who became first bishop of the See of Léon and one of the seven founder saints of Brittany. He allegedly died in 575, rumoured to have lived to the age of 140, after having been assisted in his labors by three successive coadjutors. This suggests that several Pauls have been conflated. Gilbert Hunter Doble thought that he might have been Saint Paulinus of Wales.
Brychan Brycheiniog was a legendary 5th-century king of Brycheiniog in Mid Wales.
Saint Cadoc or Cadog was a 5th–6th-century Abbot of Llancarfan, near Cowbridge in Glamorgan, Wales, a monastery famous from the era of the British church as a centre of learning, where Illtud spent the first period of his religious life under Cadoc's tutelage. Cadoc is credited with the establishment of many churches in Cornwall, Brittany, Dyfed and Scotland. He is known as Cattwg Ddoeth, "the Wise", and a large collection of his maxims and moral sayings were included in Volume III of the Myvyrian Archaiology. He is listed in the 2004 edition of the Roman Martyrology under 21 September. His Norman-era "Life" is a hagiography of importance to the case for the historicity of Arthur as one of seven saints' lives that mention Arthur independently of Geoffrey of Monmouth's Historia Regum Britanniae.
Octa was an Anglo-Saxon King of Kent during the 6th century. Sources disagree on his relationship to the other kings in his line; he may have been the son of Hengist or Oisc, and may have been the father of Oisc or Eormenric. The dates of his reign are unclear, but he may have ruled from 512 to 534 or from 516 to 540. Despite his shadowy recorded history Octa made an impact on the Britons, who describe his deeds in several sources.
Catigern is a figure of Welsh tradition, said to be a son of Vortigern, the tyrannical King of the Britons, and the brother of Vortimer. A figure of this name also appears in the Welsh genealogies, though he is given different parentage. Catigern is nearly exclusively known for a tradition in which he fell in battle with the Saxons.
Brycheiniog was an independent kingdom in South Wales in the Early Middle Ages. It often acted as a buffer state between England to the east and the powerful south Welsh kingdom of Deheubarth to the west. It was conquered and pacified by the Normans between 1088 and 1095, though it remained Welsh in character. It was transformed into the Lordship of Brecknock and later formed the southern and larger part of the historic county of Brecknockshire. To its south was the Kingdom of Morgannwg.
Athrwys ap Meurig was a prince, and possibly king, of Gwent and Glywysing in Wales. He was the son of King Meurig ap Tewdrig and the father of the later king Morgan ab Athrwys. It is possible he died before his father Meurig and did not live to rule as king himself.
Gwent was a medieval Welsh kingdom, lying between the Rivers Wye and Usk. It existed from the end of Roman rule in Britain in about the 5th century until the Norman conquest of England in the 11th century. Along with its neighbour Glywyssing, it seems to have had a great deal of cultural continuity with the earlier Silures, keeping their own courts and diocese separate from the rest of Wales until their conquest by Gruffydd ap Llywelyn. Although it recovered its independence after his death in 1063, Gwent was the first of the Welsh kingdoms to be overrun following the Norman conquest.
Meurig ap Tewdrig was the son of Tewdrig, and a king of the early Welsh kingdoms of Gwent and Glywysing. He was in power some time before 470 AD.
Glywysing was, from the sub-Roman period to the Early Middle Ages, a petty kingdom in south-east Wales. Its people were descended from the Iron Age tribe of the Silures, and frequently in union with Gwent, merging to form Morgannwg.
Gwynllyw Filwr or Gwynllyw Farfog, known in English in a corrupted form as Woolos the Warrior or Woolos the Bearded was a Welsh king and religious figure.
Gwrtheyrnion or Gwerthrynion was a commote in medieval Wales, located in Mid Wales on the north side of the River Wye; its historical centre was Rhayader. It is said to have taken its name from the legendary king Vortigern. For most of the medieval era, it was associated with the cantref of Buellt and then Elfael, small regional kingdoms whose rulers operated independently of other powers. In the Norman era, like the rest of the region between Wye and Severn it came to be dominated by Marcher Lordships.
Penychen was a possible minor kingdom of early medieval Wales and later a cantref of the Kingdom of Morgannwg. Penychen was one of three cantrefi that made up the kingdom of Glywysing, lying between the rivers Taff and Thaw, the other two being Gwynllwg and Gorfynydd. According to tradition, these cantrefi were created on the death of Glywys, the first king of Glywysing, when the kingdom was divided between his three sons: Pawl, Gwynllyw and Mechwyn. But our knowledge of the early history of the kingdom is very uncertain, being mainly sourced from medieval documents and traditional pedigrees.
Clemen ap Bledric was a 7th-century King of Dumnonia.
Ffernfael ap Tewdwr was a king of Buellt and Gwrtheyrnion in medieval Wales. Little is known of him besides a pedigree included in the 9th-century Historia Brittonum, which makes him a descendant of the ruler Vortigern.
Amlawdd Wledig was a legendary king of sub-Roman Britain. The Welsh title [G]wledig, archaically Gwledic or Guletic and Latinised Guleticus, is defined as follows: "lord, king, prince, ruler; term applied to a number of early British rulers and princes who were prominent in the defence of Britain about the time of the Roman withdrawal; (possibly) commander of the native militia ".
