King Arthur's family

King Arthur's family grew throughout the centuries with King Arthur's legend. The earliest Welsh Arthurian tradition portrays Arthur as having an extensive family network, including his parents Uther Pendragon and Eigyr (Igraine), his wife Gwenhwyfar (Guinevere), his nephew Gwalchmei (Gawain), a brother, and several sons. His maternal lineage is also detailed, linking him to relatives such as his grandfather, the legendary king Amlawdd Wledig. This complex familial structure was both simplified and expanded in shared traditions of British, French, and other medieval European chronicles and romances, which introduced new characters: Arthur's half-sisters, including Morgan, their children, including Mordred, and others. Arthur's lineage was later claimed by various rulers, in particular the House of Tudor and Scottish clans, reflecting the enduring legacy of his familial ties in medieval and early modern genealogies.
