      “WILLIAM the Conqueror, Duke (or Count) of Normandy, 1035-1087, King of England, 1066-1087, illegitimate son, probably born at Falaise 1027-1028. In 1046-7 William's right to be duke was attacked by his cousin, Guy, Count of Brionne. Guy and his associates were defeated by an army led by William and the French king Henri I to the south-west of Caen at Val-ès-Dunes. In 1049 William joined the French king's campaign against Geoffrey Martel, Count of Anjou, taking part in the successful siege of the castle of Mouliherne near Angers. He married about 1050 (marriage prohibited 1049, dispensation dated 1059, they being related by near kinship within the 7th degree) MAUD OF FLANDERS, daughter of Baudouin V, Count-Marquis of Flanders, by Adèle, daughter of Robert II, King of France [see Line B, Gen. 10 below for her parentage]. They had four sons, Robert Curthose [Duke of Normandy], Richard, William II Rufus [King of England], and Henry R] [King of England, Duke of Normandy], and five daughters, Alice (or Adelise) (nun at St Léger in Préaux), Cecily [Abbess of Holy Trinity, Caen], Maud, Constance (wife of Alan IV, Count of Brittany), and Adèle (wife of Étienne Henri, Count of Blois). In 1051 William visited England and probably received from his childless cousin, King Edward the Confessor, a promise of the English succession. According to Norman writers, Edward's brother-in-law, Harold Godwinesson (later King Harold), who accidentally visited the Norman court in 1064 or 1065, swore an oath to support William's claim to the throne of England. However, when Edward died (5 Jan. 1066), Harold was hastily anointed king (6 Jan 1066) and was accepted by the English nobility. On 28 Sept. 1066 William landed at Pevensey with his army and defeated Harold's forces in the Battle of Hastings (14 October 1066). William was crowned King of England 25 Dec. 1066. He invaded Scotland in 1072 and Wales in 1081. He spent most of his time in Normandy, but returned to England each time when it was absolutely necessary. In 1082 William imprisoned his half-brother Eudes, Bishop of Bayeux and Earl of Kent, on a charge of disloyalty. His wife, Maud, died 2 Nov. 1083, and was buried at Sainte-Trinité in Caen. Her tombstone with inscription carved round the edge has survived. In 1085 William brought a large army to meet the threat of an invasion by Canute IV of Denmark, but it never occurred. One of the most important deeds of William in his last years was ordering of economic and tenurial survey of England, the results of which were summarized in the Domesday Book. In the summer of 1086 the Conqueror departed for the continent, where he went on a military expedition to retaliate against an invading French garrison at the border town of Mantes. He was injured while riding a horse and the ailing king was carried back to Rouen and then moved for peace and quiet to the priory of Saint Gervais outside the city. Surrounded by clergy and magnates, he apparently remained lucid until the end, which came on 9 September 1087. His corpse was transported by river and sea to Caen, where he was buried in the abbey church of Saint-Étienne.
