William VII (born 
Peter, 
Pierre-Guillaume) (1023 – autumn 1058), called 
the Eagle (
Aigret) or 
the Bold (
le Hardi), was the 
duke of Aquitaine and 
count of Poitou (as William V) between 1039 and his death, following his half-brother 
Odo.
William was the third son of 
William V of Aquitaine, the eldest by his third wife, 
Agnes of Burgundy. He was brother-in-law of the 
Holy Roman Emperor Henry III, who married his sister 
Agnes. His mother remarried to 
Geoffrey Martel, 
Count of Anjou, during his reign. William won his patrimony in a war with his half-brother Odo, who was killed in battle at 
Mauzé. He did not, however, succeed in occupying Gascony.
Geoffrey Martel refused to concede to him the territories gained in 
the reigns of his predecessors. William set to work regaining his 
patrimony by force of arms. He was besieging Geoffrey in 
Saumur when he died of 
dysentery.
He was married to Ermesinde, of unknown origins. Two daughters have been hypothesized to be children of this couple:
Clementia, who married 
Conrad I of Luxembourg y Agnes, who married Peter I of Savoy.[1]  
  
William the Great (
French: 
Guillaume le Grand; 969 – 31 January 1030) was 
duke of 
Aquitaine (as 
William V) and 
count of 
Poitou (as 
William II or 
III) from 990 until his death.
[1] Upon the death of the 
emperor Henry II, he was offered the 
kingdom of Italy but eventually declined to contest the title against 
Conrad II.
He was the son and successor of 
William IV by his wife 
Emma of Blois, daughter of 
Theobald I of Blois.
[1] He seems to have taken after his formidable mother, who ruled Aquitaine as 
regent until 1004. He was a friend to Bishop 
Fulbert of Chartres, who found in him another 
Maecenas, and founded a cathedral school at 
Poitiers.
 He himself was very well educated, a collector of books, and turned the
 prosperous court of Aquitaine into the learning centre of Southern 
France.
 
Agnes of Burgundy (or 
Agnes de Macon)
, Duchess of Aquitaine (died 10 November 1068) was a duchess consort of Aquitaine by marriage to 
William V, Duke of Aquitaine and a countess consort of Anjou by marriage to 
Geoffrey II, Count of Anjou. She served as regent of the Duchy of Aquitaine during the minority of her son from 1039 until 1044. She was a daughter of 
Otto-William, Count of Burgundy[1] and 
Ermentrude de Roucy and a member of the 
House of Ivrea.
 
 William IV
William IV (937 – 3 February 994
[1]), called 
Fierebras or 
Fierebrace (meaning "Proud Arm", from the 
French Fier-à-bras or 
Fièrebrace, in turn from the 
Latin Ferox brachium), was the 
Duke of Aquitaine and 
Count of Poitou from 963 to his retirement in 990.
William's father, 
William III, abdicated to the abbey of Saint-Cyprien in 
Poitiers and left the government to Fierebras. His mother was 
Gerloc, the daughter of Duke 
Rollo of Normandy. His sister was 
Adelaide, wife of 
Hugh Capet,
 the king against whom William later battled for his duchy. His early 
reign was characterised by many wars. He fought frequently against the 
counts of Anjou, the first time against 
Geoffrey Greymantle, who had taken 
Loudun.
In 988, he went to war with the newly elected 
king of France, Hugh Capet, whom he refused to recognise. Capet had been granted Aquitaine by 
King Lothair
 before the latter had been reconciled to William's father. Capet 
renewed his claim on the great duchy and invaded it that year. A royal 
army was defeated on the plain of the 
Loire Valley. William sheltered the young 
Louis, the son of 
Charles, Duke of Lower Lorraine, the last legitimate 
Carolingian heir. He opened the 
palace of Poitiers to him and treated him as royalty, regarding him as the true heir to the 
French throne.
In 968, he married 
Emma or Emmeline,
[2] daughter of 
Theobald I of Blois and 
Luitgarde of Vermandois.
 Their marriage was stormy, in part because of William's indulgence in 
the pursuit of women and, a hunting aficionado, wild animals. She 
banished his paramours, they separated twice for long periods, and 
finally he retired to a monastery, as his father had done, leaving Emma 
to rule Aquitaine in the name of their son 
William until 1004. Their second son, Ebles, died sometime after 997.
Emma of Blois (
c. 950–27 December 1003) was Duchess consort of 
Aquitaine by marriage to 
William IV, Duke of Aquitaine. She ruled Aquitaine as regent for her son, 
William V, Duke of Aquitaine, from 996 until 1004
She was the daughter of 
Theobald I, Count of Blois and 
Luitgarde of Vermandois. In 968, she married 
William IV, Duke of Aquitaine.
 His overindulging in hunting and women offended her greatly. Around 
996, he retired to a monastery. During the course of her marriage, she 
would found the monastery of 
Saint Peter in Bourgueil. Emma then ruled Aquitaine as regent for their son 
William V.
William III (915 – 3 April 963), called 
Towhead (
French: 
Tête d'étoupe, 
Latin: 
Caput Stupe) from the colour of his hair, was the "Count of the Duchy of Aquitaine" from 959 and 
Duke of Aquitaine from 962 to his death. He was also the 
Count of Poitou (as 
William I) from 935 and 
Count of Auvergne from 950. The 
primary sources for his reign are 
Ademar of Chabannes, 
Dudo of Saint-Quentin, and 
William of Jumièges.
William was son of 
Ebalus Manzer and Emilienne. He was born in 
Poitiers.
 He claimed the Duchy of Aquitaine from his father's death, but the 
royal chancery did not recognise his ducal title until the year before 
his own death.
Shortly after the death of 
King Rudolph in 936, he was constrained to forfeit some land to 
Hugh the Great by 
Louis IV.
 He did it with grace, but his relationship with Hugh thenceforward 
deteriorated. In 950, Hugh was reconciled with Louis and granted the 
duchies of Burgundy and Aquitaine. He tried to conquer Aquitaine with 
Louis's assistance, but William defeated them. 
Lothair,
 Louis's successor, feared the power of William. In August 955 he joined
 Hugh to besiege Poitiers, which resisted successfully. William, 
however, gave battle and was routed.
After the death of Hugh, his son 
Hugh Capet was named duke of Aquitaine, but he never tried to take up his fief, as William reconciled with Lothair.
He was given the abbey of 
Saint-Hilaire-le-Grand, which remained in his house after his death. He also built a library in the 
palace of Poitiers.
His father was duke 
Ebles Manzer, who already was a man in his middle years when he was born in about 913. According to the chronicle of 
Ademar de Chabannes, William's mother was 
Geirlaug (French 
Gerloc), a daughter of 
Rollo of Normandy. (The less reliable Dodo has William rather than Ebles marrying Gerloc.)
William III married a lady named Adèle, perhaps about 936, in a match
 that may have been arranged by William I of Normandy. With Adèle, he 
had at least one child whose filiation is clearly attested:
- William, his successor in Aquitaine. He abdicated to the abbey of Saint-Cyprien in Poitiers and left the government to his son.
Many genealogies accept the high likelihood that they also had a daughter:
But her parentage is not reliably documented of their era and is 
regarded only as a good possibility by usual modern genealogical 
literature.
Gerloc (or Geirlaug), baptised in 
Rouen as 
Adela (or Adèle) in 912, was the daughter of 
Rollo, first 
duke of Normandy, and his wife, 
Poppa.
[1] She was the sister of Duke 
William Longsword.
In 935, she married 
William Towhead, the future 
count of Poitou and 
duke of Aquitaine. They had two children together before she died on 14 October 962:
Ebalus or 
Ebles Manzer or 
Manser (c. 870 – 935) was 
Count of Poitou and 
Duke of Aquitaine on two occasions: from 890 to 892; and then from 902 until his death in 935 (Poitou) and from 928 until 932 (Aquitaine).
Ebles was an illegitimate son of 
Ranulf II of Aquitaine. "Manzer" or "
Mamzer"
 is a Hebrew word that means bastard, son of a forbidden relationship, 
although in the case of Ebles it may have been applied to bastardy in 
general.
Ranulf II (also spelled 
Rannoux, 
Rannulf, 
Ramnulf, and 
Ranulph) (850 – 5 August 890) was 
Count of Poitou from 866 and 
Duke of Aquitaine from 887. On the death of 
Charles the Fat in 888, he styled himself King of Aquitaine and did so until 889 or his death, after which the title fell into abeyance.
Ranulf was a son of 
Ranulf I and Bilichild of Maine. He married an Ermengard (died 935) and by her had a son, 
Ranulf III, who succeeded him in Poitiers. His illegitimate son 
Ebalus succeeded him in Aquitaine and, upon the death of Ranulf III, in Poitiers too.
Ranulf I (also 
Ramnulf, 
Rannulf, and 
Ranulph) (820–866) was a 
Count of Poitiers (from 835) and 
Duke of Aquitaine (from 852). He is considered a possible son of 
Gerard, Count of Auvergne, and Hildegard (or Matilda) 
[more likely Rotrude, see Gerard, Count of Auvergne and Louis the Pious], daughter of 
Louis the Pious and 
Ermengard. Few details are known about Ranulf I, except that he died in 866 in 
Aquitaine from wounds received in the 
Battle of Brissarthe against the 
Vikings (in which 
Robert the Strong also died).
He married 
Bilichild of Maine and they had the following:
Gerard was 
Count of Auvergne from 839 until his death on 25 June 841.
He married first Rotrude, daughter of 
Louis the Pious. They had the following children:
He then married her sister Hildegard, they had no children.
