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 by Geoffrey of Monmouth 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.
King Arthur, according to legends, was a king of Britain. He is a folk hero and a central figure in the medieval literary tradition known as the Matter of Britain.
Uther Pendragon (Brittonic), also known as King Uther, was a legendary King of the Britons and father of King Arthur.
In the Matter of Britain, Igraine is the mother of King Arthur. Igraine is also known in Latin as Igerna, in Welsh as Eigr, in French as Ygraine, in Le Morte d'Arthur as Ygrayne—often modernised as Igraine or Igreine—and in Parzival as Arnive. She becomes the wife of Uther Pendragon, after the death of her first husband, Gorlois.
Corineus, in medieval British legend, was a prodigious warrior, a fighter of giants, and the eponymous founder of Cornwall.
Tintagel Castle is a medieval fortification located on the peninsula of Tintagel Island adjacent to the village of Tintagel (Trevena), North Cornwall in the United Kingdom. The site was possibly occupied in the Romano-British period, as an array of artefacts dating from this period have been found on the peninsula, but as yet no Roman-era structure has been proven to have existed there. It was settled during the early medieval period, when it was probably one of the seasonal residences of the regional king of Dumnonia. A castle was built on the site by Richard, 1st Earl of Cornwall in the 13th century, during the High Middle Ages. It later fell into disrepair and ruin.
Dumnonia is the Latinised name for a Brythonic kingdom that existed in Sub-Roman Britain between the late 4th and late 8th centuries CE in the more westerly parts of present-day South West England. It was centred in the area of modern Devon, but also included modern Cornwall and part of Somerset, with its eastern boundary changing over time as the gradual westward expansion of the neighbouring Anglo-Saxon kingdom of Wessex encroached on its territory. The spelling Damnonia is sometimes encountered, but that spelling is also used for the land of the Damnonii, later part of the Kingdom of Strathclyde, in present-day southern Scotland. The form Domnonia also occurs. The name of the kingdom shares a linguistic relationship with the Breton region of Domnonée.
Gurgustius was a legendary king of the Britons as accounted by Geoffrey of Monmouth. He came to power in 788BC.
Historia regum Britanniae, originally called De gestis Britonum, is a pseudohistorical account of British history, written around 1136 by Geoffrey of Monmouth. It chronicles the lives of the kings of the Britons over the course of two thousand years, beginning with the Trojans founding the British nation and continuing until the Anglo-Saxons assumed control of much of Britain around the 7th century. It is one of the central pieces of the Matter of Britain.
In Arthurian legend, Gorlois of Tintagel was the Duke of Cornwall. He was the first husband of King Arthur's mother Igraine and the father of her daughters, Arthur's half-sisters. Her second husband was Uther Pendragon, the High King of Britain and Arthur's father, who marries her after killing him.
Caradocus, according to Geoffrey of Monmouth's Historia regum Britanniae, a pseudohistorical account of the kings of the Britons, was the duke of Cornwall under the reign of Octavius, who became king of Cornwall and died during the Emperor Magnus Maximus' reign.
Dionotus was a legendary king of Cornwall in Geoffrey of Monmouth's Historia regum Britanniae, an account of the rulers of Britain based on ancient Welsh sources and disputed by many historians. Dionotus succeeding his brother Caradocus, and was regent of Britain during the campaigns in Gaul of Emperor Magnus Maximus. The curious thing about this king is that the Welsh chronicles, which parallel most of Geoffrey of Monmouth's book, do not mention this king by name. However, Geoffrey uses Latin versions of Welsh names so he could be referring to Dynod, duke of Cornwall, or Anwn Dynod, Maximus's own son.
Cador is a legendary Duke of Cornwall, known chiefly through Geoffrey of Monmouth's pseudohistorical Historia Regum Britanniae and previous manuscript sources such as the Life of Carantoc. In Welsh genealogical records, he appears as Cado, the son of Cornish king Geraint. Early sources present him as a relative of King Arthur, though the details of their kinship are usually left unspecified.
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.
King Arthur's family grew throughout the centuries with King Arthur's legend. Many of the legendary members of this mythical king's family became leading characters of mythical tales in their own right.
