Title: King Arthur's family
Content:   In Welsh Arthurian pre-Galfridian tradition, that is, from before the time of Geoffrey of Monmouth's 12th-century Historia Regum Britanniae (History of the Kings of Britain), Arthur was granted numerous relations and family members. Several early Welsh sources are usually taken as indicative of Uther Pendragon being known as Arthur's father before Geoffrey wrote, with Arthur also being granted a brother (Madog) and a nephew (Eliwlod) in these texts. Arthur also appears to have been assigned a sister in this material – Gwalchmei is named as his sister-son (nephew) in Culhwch and Olwen, his mother being one Gwyar. Culhwch and Olwen, the Vita Iltuti and the Brut Dingestow combine to suggest that Arthur's own mother was named Eigyr. The genealogies from the 13th-century Mostyn MS. 117 assert that Arthur is the 
Title: King Arthur (2004 film)
Content:  In the film, Arthur's father is a Roman general from the Imperial Roman army and his mother is a Celtic woman. In the historical notes of the legend, Arthur's father is Uther Pendragon, a famous Romano-British commander and one of Britain's earlier kings, and his mother is Igraine, a beautiful young woman who was once the wife of Gorlois, the Duke of Cornwall and one of Uther's loyal subjects. Arthur's knights are described differently in the film and the legend. In the film, Lancelot, Tristan, Bors and the other Knights of the Round Table are Sarmatian knights fighting for the glory of the Roman Empire. In historical notes, the Knights of the Round Table are Britons, knights of Romano-Celtic Britain fighting for the freedom of Britain against the Saxons. A round table is briefly present in the movie, where Arthur's knights regularly meet in equality, and which flummoxes the bishop Germanus when he cannot find a place at the table to distinguish his stature.
Title: King Arthur's family
Content:   Relatively few members of Arthur's family in the Welsh materials are carried over to the works of Geoffrey of Monmouth and chivalric romancers. His grandfather Anlawd Wledic and his maternal uncles, aunts and cousins do not appear there, and neither do any of his sons or his paternal relatives. Only the core family seem to have made the transition: his wife Gwenhwyfar (who became Guinevere), his father Uther, his mother Eigyr (Igerna) and his sister-son Gwalchmei (Gawain). Gwalchmei's mother – Arthur's sister – failed to make the journey, Gwyar's place being taken by Anna, the wife of Loth, in Geoffrey's account, whilst Modredus (Mordred) is made into a second sister-son for Arthur (a status he did not have as Medraut in the Welsh material).  In addition,

Content:  of Uthyr, the son of Custennin, the son of Cynfawr, the son of Tudwal, the son of Morfawr, the son of Eudaf, the son of Cadwr, the son of Cynan, the son of Caradoc, the son of Bran, the son of Llŷr. Regarding Arthur's own family, his wife is consistently stated to be Gwenhwyfar, usually the daughter of King Ogrfan Gawr (variation: 'Gogrfan Gawr', "[G]Ogrfan the Giant") and sister to Gwenhwyfach, although Culhwch and Bonedd yr Arwyr do indicate that Arthur also had some sort of relationship with Eleirch daughter of Iaen, which produced a son named Kyduan (Cydfan). Kyduan was not the only child of Arthur according to Welsh Arthurian tradition – he is also ascribed sons called Amr (Amhar), Gwydre, Llacheu and Duran. (See the Offspring section for 
Title: King Arthur
Content:   Geoffrey of Monmouth's Historia Regum Britanniae, completed, contains the first narrative account of Arthur's life. This work is an imaginative and fanciful account of British kings from the legendary Trojan exile Brutus to the 7th-century Welsh king Cadwallader. Geoffrey places Arthur in the same post-Roman period as do Historia Brittonum and Annales Cambriae. He incorporates Arthur's father Uther Pendragon, his magician advisor Merlin, and the story of Arthur's conception, in which Uther, disguised as his enemy Gorlois by Merlin's magic, sleeps with Gorlois's wife Igerna (Igraine) at Tintagel, and she conceives Arthur. On Uther's death, the fifteen-year-old Arthur succeeds him as King of 
Title: Hawk of May
Content:  Morgawse, Gwalchmai's mother and Uther's legitimate daughter, is the brain behind Lot's brawn. She is later revealed to channel a spirit called the Queen of Air and Darkness. She hates Arthur, at least in part because she believes that Lot, through her, has a better claim to be High King. ; Medraut is the younger brother of Gwalchmai. As a young child, he looks up to Gwalchmai. Medraut eventually replaces Gwalchmai in Morgawse's schemes and becomes enthralled by the darkness. ; Arthur is the bastard son of Uther Pendragon. Other than his unexplained anger towards Gwalchmai, Arthur is an honorable and farsighted leader who dreams of a united, peaceful Britain. ; Cei is Arthur's infantry 
Title: Morgause
Content:  The Queen of Orkney, today best known as Morgause and also known as Morgawse and other spellings and names, is a character in later Arthurian traditions. In some versions of the legend, including the seminal text Le Morte d'Arthur, she is the mother of Gawain and Mordred, both key players in the story of King Arthur and his downfall. Mordred is the offspring of Arthur's accidental incest with Morgause, the king's estranged half-sister. She is furthermore a sister of Morgan le Fay and the wife of King Lot of Orkney, as well as the mother of Gareth, Agravain, and Gaheris, the last of whom murders her.
Title: Arthur, Prince of Wales
Content:  Arthur Tudor (19/20 September 1486 – 2 April 1502) was Prince of Wales, Earl of Chester and Duke of Cornwall. As the eldest son and heir apparent of Henry VII of England, Arthur was viewed by contemporaries as the great hope of the newly established House of Tudor. His mother, Elizabeth of York, was the daughter of Edward IV, and his birth cemented the union between the House of Tudor and the House of York. Plans for Arthur's marriage began before his third birthday; he was installed as Prince of Wales two years later. At the age of eleven, he was formally betrothed to Catherine of Aragon, a daughter of the powerful Catholic Monarchs in Spain, in an effort to forge an Anglo-Spanish alliance against France. Arthur was well educated and was in good health for the majority of his life. Soon after his marriage 
Title: The Faerie Queene
Content:  The Faerie Queene owes, in part, its central figure, Arthur, to a medieval writer, Geoffrey of Monmouth. In his Prophetiae Merlini ("Prophecies of Merlin"), Geoffrey's Merlin proclaims that the Saxons will rule over the Britons until the "Boar of Cornwall" (Arthur) again restores them to their rightful place as rulers. The prophecy was adopted by the Welsh and eventually used by the Tudors. Through their ancestor, Owen Tudor, the Tudors had Welsh blood, through which they claimed to be descendants of Arthur and rightful rulers of Britain. The tradition begun by Geoffrey of Monmouth set the perfect atmosphere for Spenser's choice of Arthur as the central figure and natural bridegroom of Gloriana.
Title: Mordred
Content:   Traditions vary on Mordred's relationship to Arthur. Medraut is never considered Arthur's son in Welsh texts, only his nephew, though The Dream of Rhonabwy mentions that the king had been his foster father. In early literature derived from Geoffrey's Historia, Mordred was considered the legitimate son of Arthur's sister or half-sister queen variably known as Anna or Morgause (Orcades / Morcades / Morgawse / Margawse) with her husband, Lot (Loth), the king of either Lothian or Orkney. Today, however, he is best known as Arthur's own illegitimate son by Morgause in the motif introduced in the Vulgate Cycle, in which their union happens
