      “ROBERT I the Magnificent, Count of Hiémois, 1026, Duke of Normandy, 1027-1035, 2nd son. He was heir in 1027 to his older brother, Richard (III), Duke of Normandy. By his mistress, ARLETTE (or HERLEVE), daughter of Fulbert of Falaise, he had one illegitimate son, William the Conqueror [King of England, Duke of Normandy], and also by Arlette or an unknown mistress, one illegitimate daughter, Alice [Countess of Aumale]. ROBERT I, Duke of Normandy; set off on a pilgrimage to Jerusalem early in 1035, and subsequently died at Nicaea 1-3 July 1035. Herleve married c.1030 HERLUIN DE CONTEVILLE, Vicomte, seigneur of Conteville. They had two sons, Eudes [Bishop of Bayeux, Earl of Kent] and Robert [Count of Mortain], and one daughter, Muriel. He founded Grestain Abbey in Normandy about 1050. He and his wife renounced their claim to the tithe of Toutainville and to the vill called Mesnil-Dastin to Preaux Abbey. His wife, Herleve, is thought to have been living in 1050-51, but died soon afterwards. He married (2nd) FREDESENDE ___. They had two sons, Jean (who appears to have died young) and Raoul Fitz Herluin (or de Conteville) [seigneur of Corneville-sur-Risle and Martainville-en-Lieuvin, presumably Domesday tenant of Chapel Allerton, Huish (in Burnham), Adber (in Trent), and Brent, Somerset]. HERLUIN DE CONTEVILLE died about 1066. He and his first wife, Arlette, were buried in Grestain Abbey. His widow, Fredesende, granted part of dower lands at Le Neubourg, Cantelou, and Honnaville (dep. Calvados) to Grestain Abbey.

      Child of Robert of Normandy, by Herleve of Falaise:
      i. WILLIAM, Duke of Normandy, King of England [see next].
      Child of Robert of Normandy, by a mistress, possibly Herleve of Falaise:
      i. ALICE (AELIDIS, ADELIZA, ADELISA, ADELIDIS) OF NORMANDY, born before 1035. She married (1st) ENGUERRAND II, Count of Ponthieu, son and heir of Hugues II, Count of Ponthieu and Montreuil, seigneur of Abbeville, by Berthe, daughter of Guérinfrid, seigneur of Aumale. They had one daughter, Alice. He was slain before the Château d'Arques 25 October 1053. His widow, Alice, married (2nd) 1053/4 LAMBERT OF BOULOGNE, Count of Lens, Governor of Lille Castle, younger son of Eustache I, Count of Boulogne, by Mathilde (or Mahaut), daughter of Lambert I, Count of Louvain [see BOULOGNE 1 for his ancestry]. They had one daughter, Judith. In 1047 he and his brother, Count Eustache, and Count Baldwin V of Flanders were in attendance at the court of King Henry III of Germany, where they witnessed Henry's confirmation of a gift to St. Medard. LAMBERT OF BOULOGNE, Count of Lens, was slain in battle at Phalempin in 1054. His widow, Alice, married (3rd) in 1060 EUDES III, Count of Champagne, Banner-bearer to the Archbishops of Rouen, son and heir of Étienne, Count of Troyes and Meaux, by his wife, Adelaide. They had one son, Stephen (or Étienne) [Count of Aumale]. In the period, 1047-55, he witnessed an agreement between Rahier, husband of Arembourg, and the canons of Saint-Maurice of Angers, by which the canons temporarily relinquished certain rights in the church of Joué. At the death of his father about 1047 or 1048, he was deprived of the county of Champagne by his uncle, Thibaut III, and took refuge with William, Duke of Normandy [afterwards William the Conqueror, King of England]. William gave him his sister, Alice, in marriage. After the conquest of England in 1066, in which Eudes rendered good service, King William granted him the lordship of Holderness in England. William also erected the terrritory of Aumale into a county, which lands had been given to Eudes by Jean de Bayeux, Archbishop of Rouen. In 1082 William I, King of England, gave the Abbey of Holy Trinity at Caen the bourg of Le Homme with its revenues, with a reservation in favor of his sister, Alice, Countess of Aumale, of the tenancy during her life. Alice, Countess of Aumale, was living in 1086, and died before 1096 (date of charter). Sometime in the period, 1087-1095, Eudes witnessed a charter of King William Rufus, confirming to the Abbey of Saint Pierre au Mont Blandin in Gand certain possessions in his kingdom. Following the death of King William the Conqueror in 1087, he supported William Rufus as king in opposition to Robert, Duke of Normandy. In 1095 he joined the rebellion of Robert de Mowbray against King William Rufus, for which he was imprisoned by William and continued in confinement the remainder of his life. Eudes, Count of Champagne, died in prison sometime between Jan. 1096 and 2 August 1107. Du Plessis Histoire de l'Église de Meaux 2 (1731): 8.

      Children of Herleve of Falaise, by Herluin de Conteville:
      i. EUDES, Bishop of Bayeux, Earl of Kent. He was an uterine half-brother of King William the Conqueror. In 1049, while still a youth, he was granted the see of Bayeux. His active career was that of a warrior and statesman. He found ships for the invasion of England and fought in person at Senlac. He became Earl of Kent in 1066-67, and for some years he was a trusted royal minister. He acquired lands in more than twenty English counties. He worked energetically to build up the resources, both material and spiritual, of his see. At times he acted as viceroy in King William's absence and led royal forces to chastise rebellions. He took part in the northern campaign with his nephew, Robert Curthose, in 1080. In 1083 he was suddenly disgraced and imprisoned on the king's orders. In 1087 King William, when on his death-bed, reluctantly permitted his release. In 1088 he supported the rebellion of Robert Curthose against King William Rufus. In 1096 he went on the 1st Crusade. EUDES, Bishop of Bayeux, died in Jan. 1097 while visiting Sicily, and was buried in Palermo Cathedral. By an unknown mistress, he had one illegitimate son, John.

      “ALICE (AELIDIS, ADELIZA, ADELISA, ADELIDIS) OF NORMANDY, illegitimate daughter of Robert, Duke of Normandy, possibly by his mistress, Arlette (or Harleve) [see Appendix, Line A, Gen. 11 for her ancestry], born before 1035. She was the sister of William the Conqueror, King of England [see ENGLAND 1]. She married (1st) ENGUERRAND II, Count of Ponthieu, son and heir of Hugues II, Count of Ponthieu and Montreuil, seigneur of Abbeville, by Berthe, daughter of Guerinfrid, seigneur of Aurnale. They had one daughter, Alice. He was slain before the Chateau d'Arques 25 October 1053. His widow, Alice, married (2nd) 1053/4 LAMBERT OF BOULOGNE, Count of Lens, Governor of Lille Castle, younger son of Eustache I, Count of Boulogne, by Mathilde (or Mahaut), daughter of Lambert I, Count of Louvain [see BOULOGNE 1 for his ancestry]. They had one daughter, Judith. In 1047 he and his brother, Count Eustache, and Count Baldwin V of Flanders were in attendance at the court of King Henry III of Germany, where they witnessed Henry's confirmation of a gift to St. Medard. LAMBERT OF BOULOGNE, Count of Lens, was slain in battle at Phalempin in 1054. His widow, Alice, married (3rd) in 1060 EUDES III, Count of Champagne, Banner-bearer to the Archbishops of Rouen, son and heir of Etienne, Count of Troyes and Meaux, by his wife, Adelaide. They had one son, Stephen (or Etienne) [Count of Aumale]. In the period, 1047-55, he witnessed an agreement between Rahier, husband of Arembourg, and the canons of Saint-Maurice of Angers, by which the canons temporarily relinquished certain rights in the church of Joué. At the death of his father about 1047 or 1048, he was deprived of the county of Champagne by his uncle, Thibaut III, and took refuge with William, Duke of Normandy [afterwards William the Conqueror, King of England]. William gave him his sister, Alice, in marriage. After the conquest of England in 1066, in which Eudes rendered good service, King William granted him the lordship of Holderness in England. William also erected the territory of Aumale into a county, which lands had been given to Eudes by Jean de Bayeux, Archbishop of Rouen. In 1082 William I, King of England, gave the Abbey of Holy Trinity at Caen the bourg of Le Homme with its revenues, with a reservation in favor of his sister, Alice, Countess of Aumale, of the tenancy during her life. His wife, Alice, Countess of Aumale, was living in 1086, and died before 1096 (date of charter). Sometime in the period, 1087-1095, Eudes witnessed a charter of King William Rufus, confirming to the Abbey of Saint Pierre au Mont Blandin in Gand certain possessions in his kingdom. Following the death of King William the Conqueror in 1087, he supported William Rufus as king in opposition to Robert, Duke of Normandy. In 1095 he joined the rebellion of Robert de Mowbray against King William Rufus, for which he was imprisoned by William and continued in confinement the remainder of his life. Eudes, Count of Champagne, died in prison sometime between Jan. 1096 and 2 August 1107.

      “WILLIAM the Conqueror, Duke (or Count) of Normandy, 1035-87, King of England, 1066-87, illegitimate son of Robert, Duke of Normandy, by his mistress, Axlette (or Herleve) [see Appendix, Line A for his ancestry]. He was probably born at Falaise 1027-28. 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-es-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 Mouliheme 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 Adele, daughter of Robert II, King of France [see Appendix, Line B for her ancestry]. They had four sons, Robert Curthose puke of Normandy], Richard, William II Rufus [King of England], and Henry [I] [King of England, Duke of Normandy, Count of Cotentin], and five daughters, Alice (or Adelise) (nun at St Leger in Preaux), Maud, Constance, Cecily [Abbess of Holy Trinity, Caen], and Adele (wife of Etienne Henri, Count of Blois). In 1051 William visited England and probably received a promise of the English succession from his childless cousin, King Edward the Confessor. According to Norman writers, King Edward's brother-in-law, Harold Godwinesson (later King Harold), who visited the Norman court in 1064 or 1065, swore an oath to support William's claim to the throne of England. However, when King Edward died (5 Jan 1066), Harold was hastily anointed king (6 Jan 1066) and was accepted by the English nobility. On 28 September 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 in Westminster Abbey 25 December 1066 by Aldred, Archbishop of York. 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. He was a major patron of monasteries, founding two great abbeys at St Etienne of Caen and Battle, and making donations to a host of other churches. His wife, Maud, died 2 November 1083, and was buried at Sainte-Trinite 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-Etienne.
