Although Arthur is given sons in both early and late Arthurian tales, he is rarely has many generations of offspring. This is at least partly because of the usually premature deaths of Arthur's sons. In some cases, including in ''Le Morte d'Arthur'', Arthur's failure to produce a legitimate heir contributes to his fall. In the early Welsh tradition, Mordred (Medraut) was a nephew of Arthur, before later becoming Arthur's child. Instead, Arthur has a number of different sons but their stories are largely lost. Amr is the first of them to be mentioned in Arthurian literature, appearing in the 9th-century
Historia Brittonum: Why Arthur chose or was forced to kill his son is never made clear. The only other reference to Amr comes in the post-Galfridian Welsh romance
Geraint, where "Amhar son of Arthur" is one of Arthur's four chamberlains, along with
Bedwyr's son Amhren.Another son, Gwydre, suffers a similarly premature death, being slaughtered by the giant boar
Twrch Trwyth in
Culhwch and Olwen, along with two of Arthur's maternal uncles. No other references to either Gwydre or Arthur's uncles survive. More is known about Arthur's son Llacheu. He is one of the "Three Well-Endowed Men of the Island of Britain", according to
Triad 4, and he fights alongside
Cei in the early Arthurian poem
Pa gur yv y porthaur?. Like his father is in
Y Gododdin, Llacheu frequently appears as a heroic figure in early Welsh literature, and is also appears in local folklore lied to specific locations. Because of this, there is general consensus that Llacheu was a relatively major character in early Arthurian mythology. Nonetheless, Llacheu too dies, with the speaker in the pre-Galfridian poem
Ymddiddan Gwayddno Garanhir ac Gwyn fab Nudd remembering that he had "been where Llacheu was slain / the son of Arthur, awful in songs / when ravens croaked over blood." The romance character based on him, known as
Lohot or similar names, usually also dies young. Mordred is a major exception to this tradition of Arthur's sons dying childless. According to Geoffrey of Monmouth and the post-Galfridian tradition, Mordred (like Amr) is killed by Arthur, this time dying at Camlann. However, unlike the others, he has
two sons, who both rose against Arthur's successor and cousin
Constantine III with the help of the Saxons. However, in Geoffrey's
Historia (where the motifs of Arthur's killing of Mordred and Mordred's sons first appear), Mordred was not Arthur's son. His relationship with Arthur was reinterpreted in the
Vulgate Cycle, as he was made the result of an unwitting incest between Arthur and his sister. This tale is preserved in the later romances, so by the time of the
Post-Vulgate Cycle, a tale emerges where
Merlin tells Arthur that Mordred would grow up to destroy him. In this story, Arthur devises
Herod-like plot to rid of all of his children on the same day to try to save himself from this fate. The Post-Vulgate version also features another of Arthur's illegitimate sons,
Arthur the Less, who survives for as long as Mordred but remains fiercely loyal to Arthur. Other literature further expanded Arthur's immediate family. His daughter, Archfedd, is found in only one Welsh source, the 13th-century
Bonedd y Saint. A daughter named Hild[e] is mentioned in the 13th-century Icelandic
Þiðreks saga (
Thidrekssaga), while the
Möttuls saga from around the same period features a son of Arthur named Aristes. Arthur's son, Samson the Fair, for whom the Norse story
Samsons saga fagra is named, also has a sister named Grega. Rauf de Boun's 1309
Petit Brut lists Arthur's son Adeluf III as a king of Britain, also mentioning Arthur's other children, Morgan le Noir (Morgan the Black), and Patrike le Rous (Patrick the Red) by an unnamed
Fairy Queen. Later on, a number of
early modern works have occasionally give Arthur more or different sons and daughters. ==Bloodline claims==
