Question: The last descendant of the leader of the Anglo-Saxon settlement of Britain was never what?

full_context: Document 1: Æthelstan Half-King: Æthelstan (fl. 932 - 956), was an important and influential Ealdorman of East Anglia who interacted with five kings of England, including his adopted son Edgar the Peaceful. Many of Æthelstan's close relatives were also involved in important affairs, but soon after the death of king Eadred in 955, he left his position and became a monk at Glastonbury Abbey.
Document 2: Edmund Ironside: Edmund II (died 30 November 1016), usually known as Edmund Ironside, was King of England from 23 April to 30 November 1016. He was the son of King Æthelred the Unready and his first wife, Ælfgifu of York. Edmund's reign was marred by a war he had inherited from his father, his cognomen "Ironside" was given to him "because of his valour" in resisting the Danish invasion led by Cnut the Great.
Document 3: History of Herefordshire: The History of Herefordshire starts with a shire in the time of Athelstan (895–939), and Herefordshire is mentioned in the "Anglo-Saxon Chronicle" in 1051. The first Anglo-Saxon settlers, the Magonsætan, were a sub-tribal unit of the Hwicce who occupied the Severn valley. The Magonsætan were said to be in the intervening lands between the Rivers Wye and Severn. The undulating hills of marl clay were surrounded by the Welsh mountains to the west; the Malvern Hills to the east; the Clent Hills of the Shropshire borders to the north, and the indeterminate extent of the Forest of Dean to the south. The shire name first recorded in the "Anglo-Saxon Chronicle" was derived from "Here-ford", Old English for "Army crossing", the location for the city. The area was covered first by Offa of Mercia, who constructed the dyke as a boundary to keep warring tribes out of the Mercian kingdom: an early indication of the ambivalent relations with the Welsh. The shire as an administrative unit was developed from Alfred the Great's Burghal Hidage, and the Shire-reeve courts of the Hundred. King Edgar the Ætheling was a regular visitor, and founded the diocese, previously part of the see of Worcester, in 976. The establishment of a centre of law and justice was supported by a monastic chapter that flourished during the Tenth century Reformation. Hereford's geographical location at the hub of the shire allowed Anglo-Saxon ealdormen to manage affairs; and Hereford played a vital role in the Scandinavian wars until Ralph, Earl Hereford was deposed by the regal Earl Harold Godwinson.
Document 4: Edward the Confessor: Edward the Confessor (Old English: "Ēadƿeard Andettere" ] , Latin: "Eduardus Confessor" ] ; c. 1003 – 5 January 1066), also known as Saint Edward the Confessor, was among the last Anglo-Saxon kings of England. Usually considered the last king of the House of Wessex, he ruled from 1042 to 1066.
Document 5: Edward the Exile: Edward the Exile (1016 – 19 April 1057), also called "Edward Ætheling", was the son of King Edmund Ironside and of Ealdgyth. He spent most of his life in exile in the Kingdom of Hungary following the defeat of his father by Canute the Great.
Document 6: Cerdic of Wessex: Cerdic (] ) is cited in the "Anglo-Saxon Chronicle" as a leader of the Anglo-Saxon settlement of Britain, being the founder and first king of Saxon Wessex, reigning from 519 to 534. Subsequent kings of Wessex all had some level of descent claimed in the Chronicle from Cerdic. (See House of Wessex family tree)
Document 7: Cherin: Cherin was a legendary king of the Britons as recounted in Geoffrey of Monmouth's "Historia Regum Britanniae". His father was King Porrex II and he was succeeded by his three sons in turn, Fulgenius, Edadus, and Andragius.
Document 8: Kings of the Angles: The Angles were a dominant Germanic tribe in the Anglo-Saxon settlement of Britain, and gave their name to the English, England and to the region of East Anglia. Originally from Angeln, present-day Schleswig-Holstein, a legendary list of their kings has been preserved in the heroic poems "Widsith" and "Beowulf", and the "Anglo-Saxon Chronicle".
Document 9: Ancestry of the Godwins: Very little is known for certain of the ancestry of the Godwins, the family of the last Anglo-Saxon King of England, Harold II. When King Edward the Confessor died in January 1066 his closest relative was his great-nephew, Edgar the Ætheling, but he was young and lacked powerful supporters. Harold was the head of the most powerful family in England and Edward's brother-in-law, and he became king. In September 1066 Harold defeated and killed King Harald Hardrada of Norway at the Battle of Stamford Bridge, and Harold was himself defeated and killed the following month by William the Conqueror at the Battle of Hastings.
Document 10: Southumbrians: The Southumbrians or 'Suðanhymbre' were the Anglo-Saxon people occupying northern Mercia. The term might not have been used by the Mercians, and instead possibly coined by the Deiran or Bernician people as a territorial response to their own Kingdom of Northumbria. The "Anglo-Saxon Chronicle" refers to King Coenred as having become the King of the Southumbrians in 702, two years before he became King of all the Mercians. The fact that Coenred was the son of Wulfhere, the Mercian King, implies that Southumbria was a sub-kingdom of Mercia.
Document 11: Saxons: The Saxons (Latin: "Saxones" , Old English: "Seaxe" , Old Saxon: "Sahson" , Low German: "Sassen" , German: "Sachsen" , Dutch: "Saksen" , Welsh: "Saeson" ) were a group of Germanic tribes first mentioned as living near the North Sea coast of what is now Germany (Old Saxony), in the late Roman empire. They were soon mentioned as raiding and settling in many North Sea areas, as well as pushing south inland towards the Franks. Significant numbers settled in large parts of Great Britain in the early Middle Ages and formed part of the merged group of Anglo-Saxons who eventually organised the first united Kingdom of England. Many Saxons however remained in Germania (Old Saxony c. 531-804), where they resisted the expanding Frankish Empire through the leadership of the semi-legendary Saxon hero, Widukind. Initially, Saxons of Britain and those of Old Saxony (Northern Germany) were both referred to as 'Saxons' in an indiscriminate manner. The term Anglo-Saxon, in turn, came into practice in the 8th century (probably by Paul the Deacon) to distinguish English Saxons from continental Saxons (Ealdseaxe, 'old Saxons').
Document 12: Edgar Ætheling: Edgar Ætheling (also spelt Æþeling, Aetheling, Atheling or Etheling) or Edgar II (c. 1051 – c. 1126) was the last male member of the royal house of Cerdic of Wessex (see House of Wessex family tree). He was proclaimed, but never crowned, King of England in 1066.
Document 13: Æthelred the Unready: Æthelred II, also dubbed the Unready (Old English: Æþelræd, ] ), (  966 – 23 April 1016) was King of the English (978–1013 and 1014–1016). He was the son of King Edgar the Peaceful and Queen Ælfthryth and was around 12 years old when his half-brother Edward the Martyr was murdered on 18 March 978. Although Æthelred was not personally suspected of participation, the murder was committed at Corfe Castle by his attendants, making it more difficult for the new king to rally the nation against the military raids by Danes, especially as the legend of St Edward the Martyr grew.
Document 14: Anglo-Saxons: The Anglo-Saxons were a people who inhabited Great Britain from the 5th century. They comprise people from Germanic tribes who migrated to the island from continental Europe, their descendants, and indigenous British groups who adopted some aspects of Anglo-Saxon culture and language. Historically, the Anglo-Saxon period denotes the period in Britain between about 450 and 1066, after their initial settlement and up until the Norman conquest.
Document 15: Edmund Ætheling: Edmund Ætheling ( ;  1015–17 – possibly 1046, certainly by 1054) was a member of the royal House of Wessex as the son of Edmund Ironside, who briefly ruled as King of England between April and November 1016. He fought the Danish Vikings under Cnut the Great, but following the Danish victory at the Battle of Assandun in October, it was agreed that Ironside would rule Wessex, while Cnut took Mercia and probably Northumbria. In November 1016, Ironside died and Cnut became King of all England.
