  William III (913 – 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[1] 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 cede 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.
  
  Family background, marriage and issue
  
  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 wife was Geirlaug (French: Gerloc, also known as Adèle), a daughter of Rollo of Normandy. The less reliable Dudo of Saint-Quentin has William rather than Ebles marrying Gerloc, perhaps about 936, in a match that may have been arranged by William I of Normandy.
  
  With Gerloc, 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[who?] genealogies accept the high likelihood[vague] that they also had a daughter:
  
  Adelaide, who married Hugh Capet
  But her parentage is not reliably documented of their era and is regarded only as a good possibility by usual modern genealogical literature.
  
  Wilhelm Werghaupt (lat. Caput stupe, frz. Tête d'Etoupe; * um 900; † 3. April 963) war als Wilhelm III. Herzog von Aquitanien und als Wilhelm I. Graf von Poitou, Limoges und Auvergne aus der Familie der Ramnulfiden.
  
  Wilhelm war der älteste Sohn von Ebalus Mancer, dem er nach dessen Tod 934 im Poitou nachfolgte. Wilhelm war ein Feind der Robertiner, deren Oberhaupt Hugo Magnus sich 936 Poitiers bemächtigte. Unter Ausnutzung des Konfliktes Hugos mit König Ludwig IV. dem Überseeischen konnte Wilhelm die Stadt 938 zurückerobern. 942 wurde er vom König zum Laienabt der Abtei von St. Hilaire ernannt, die seither im Besitz der Familie blieb.
  
  Seinen vorrangigsten Kampf führte Wilhelm gegen den Grafen Raimund Pons von Toulouse, der ihm die Herrschaft über die Auvergne streitig machte. Nach dem Tod König Ludwigs IV. (954) huldigte ihm aber die Noblesse der Auvergne, 955 erlangte er die Herrschaft über die Grafschaft Limoges. Seine Position als Herzog von Aquitanien war jedoch umstritten: Einerseits durch die Grafen von Toulouse, die 935 das Herzogtum von König Rudolf verliehen bekamen, und vor allem durch Hugo Magnus, der seinen dominierenden Einfluss auf König Lothar geltend machte und sich von diesem mit dem aquitanischen Herzogtum belehnen ließ. 955 zog Hugo Magnus mit einem königlichen Heer vor Poitiers und schlug Wilhelm in einer Feldschlacht. Poitiers konnte aber erfolgreich verteidigt werden. 956 starb Hugo Magnus und obwohl dessen Sohn Hugo Capet die Politik des Vaters aufnahm, sollte die Herrschaft Wilhelms in Aquitanien nicht mehr gefährdet werden. Erst jetzt war er unbestrittener „Herzog der Aquitanier“.
  
  Kurz vor seinem Tod wurde Wilhelm Mönch in der Abtei von Saint-Cyprien, wo er auch bestattet wurde.
  
  Wilhelm war seit 935 mit Gerloc-Adele († nach 969) verheiratet, einer Tochter des normannischen Grafen Rollo. Sie hatten zwei Kinder:
  
  Wilhelm Eisenarm (* um 937; † 995/996), Graf von Poitou (Wilhelm II.) und Herzog von Aquitanien (Wilhelm IV.)
  Adelheid (Aelis) (* wohl 950; † 1004) ∞ im Sommer 968 mit Hugo Capet, Herzog von Franzien und ab 987 König von Frankreich

   Note: GUILLAUME de Poitou, son of EBALUS "Mancer" Comte de Poitou & his [second wife Emillane ---] ([900]-Poitiers 3 Apr 963, bur Saint-Cyprien). The Chronicle of Adémar de Chabannes names "Willelmus…cognomento Caput stupe" as one of the two sons of "Eblo duce", specifying that he was "Arvernis, Vallatis, Lemovice et Pictavis comes…dux Aquitaniæ"[353]. The Chronico Comitum Pictaviæ names "Willelmum Caput-stupæ" as son of "Ebles Dux Aquitaniæ et Pictaviæ Comes" & his wife Adellia[354]. Ademar names "Willelmum Caputstupæ" as son of Eble and "Adelam, filiam Rosi Rotomagensis", but evidently confuses the latter with Guillaume's own wife[355]. He succeeded his father as GUILLAUME I “Tête d'Etoupes/Caput-stupæ” Comte de Poitou. He was appointed lay abbot of Saint-Hilaire-de-Poitiers in Jan 942[356]. From the start of his reign, his possession of Poitou was disputed by Hugues "le Grand" Duc des Francs [Capet][357]. "Guillelmus comes vel abba summi pontificis domni nostri Hylarii" donated property "in pago Pictavo in viccaria Pictavis" to the church of Saint-Hilaire de Poitiers by charter dated Jun 941 or 942[358]. Louis IV King of France confirmed the property of Saint-Hilaire de Poitiers, in the presence of "Guillelmus comes et marchio et frater eius Ebolus atque Rotgarius comes", by charter dated 5 Jan 942[359]. Comte d'Auvergne et de Limoges 955. Around this same time, Lothaire King of France extended the authority of Comte Guillaume over the whole of Aquitaine. Although known to history as GUILLAUME III Duke of Aquitaine, charters record him as "Guillelmus…Aquitanici ducatus comes"[360] and "Guillelmus…Pictavensium sive Lemovicensium necne et Arvernensium comes insuper etiam Aquitainiæ comes palati"[361] as well as "Willelmi duci Aquitanorum cognomento Caput-Stupæ"[362]. He abdicated in 962, and became a monk at Saint-Cyprien de Poitiers[363]. The Chronicle of Adémar de Chabannes records that "Willelmo Capite stupæ" was buried "apud ecclesiam Sancti Cypriani"[364]. m ([935]) ADELA [Gerloc] de Normandie, daughter of ROBERT I [Rollo] Comte [de Normandie] & his [second] wife Popa [de Bayeux] (-after 969). Guillaume de Jumièges records that Rollo captured “Baiocasensem urbem” [Bayeux] along with "nobilissimam puellam...Popam filiam...Berengarii illustris viri" whom he married “more Danico” and by whom he had “Willelmum...filiamque...Gerloc”[365]. Robert of Torigny also names "Willermum Longum Spatam et Gerloch" as children of "Rollo dux Northmannorum" and Poppa[366]. Guillaume of Jumièges records the marriage of “dux...sororem eius...Gerlco” and "Willelmus Pictavensis comes”[367]. The Chronicle of Adémar de Chabannes records the marriage of "filius Ranulfi Eblus" and "Adelam filiam Rosi Rotomagensis"[368]. The Chronico Richardi Pictavensis also records that "Heblus…Pictavorum Comes et Dux Aquitaniæ duxit Adelam filiam Rolli Rothomagensis"[369]. This information is contradicted by other sources, is difficult to sustain from a chronological point of view, and is presumably in error. Guillaume of Jumièges records the marriage of “dux...sororem eius...Gerlco” and "Willelmus Pictavensis comes”[370]. She adopted the name ADELA when baptised. "Guillelmi comitis, Adeleidis comitisse" subscribed a charter recording a donation to Cluny dated [963][371]. On 14 Oct 962, Lothaire King of France granted her the right to dispose of extensive property in Poitiers, la Cour de Faye, effectively putting an end to the long dispute between her husband and the family of Hugues "Capet". She used the property to found the Monastery of Sainte-Trinité[372]. "Vuillelmus dux Aquitanorum" donated property to Saint-Jean d'Angély for the soul of "…matre mea Addela…" by charter dated [971][373]. Duke Guillaume III & his wife had two children: 1. GUILLAUME de Poitou ([937]-Saint-Maixent [end 995/early 996], bur Abbaye de Saint-Maixent[374]). 2. [ADELAIS de Poitou ([950/55]-[1004]).
