William III was known as Tête d’étoupe (‘tow head’) because of his fair hair.

He is my 27 x great-grandfather.

William, or Guillaume, was born in Poitiers, France in 900, son of Ebalus Manzer and Emilienne¹.

Titles

In 942, he was appointed lay abbot of Saint-Hilaire-de-Poitiers¹.

He later succeeded his father as Count of Poitiers¹ but I don’t know when this happened¹. Poitiers, at the time, was sparsely populated due to recent wars, and the Viking invasions².

In 955 he became Count of Auvergne and Limoges¹. King Lothair extended William’s authority over the whole of Aquitaine, but it took till 959 for him to succeed as William III, Duke of Aquitaine¹.

Family

In 935, he married Adele, or Adela (also known as Gerloc), daughter of Rollo the Viking^{1 3 4}.

By marrying Adele, William married the daughter of the person his father had gone to war with at the Battle of Chartres.

They had two children¹:

1. William, who became William IV.
2. Adelais

Notable events

William appointed two Viscounts to help protect his eastern borders. His viscount at Châtellerault protected the frontier towards Touraine in the north². The viscount at Brosse served as a check on the counts of La Marche² in the East.

In 941 or 942, William donated land to Saint-Hilaire-de-Poitiers. Records describe it as the “vicarage of Poitou in the village of Poitiers.”¹. It is unclear if they made him a lay abbot before or after this donation. The King of France, Louis IV, confirmed this donation in a charter dated 5 January 942¹.

In 962, William abdicated and became a monk at Saint-Cyprien-de-Poitiers¹.

Death

William III died in Aquitaine, France, on 3 April 963. I don’t know how he died but they buried him in Saint-Cyprien-de-Poitiers¹.

Lineage

He is my 27 x great-grandfather.
