William VI of Angoulême
William VI of Angoulême (d. 1178) was also known as William Taillefer IV. He was the Count of Angoulême from 1140 to 1178. He inherited the title and territory from his father, Wulgrin II of Angoulême.
It is from him, that the territory was passed down through three brothers, all sons of William VI: Wulgrin III of Angoulême who was the eldest, William VII of Angoulême and Aymer of Angoulême.
After the death of Aymer, the territory did not pass to Aymer's daughter, Isabella of Angoulême, Queen consort to John of England, but rather to the daughter of Wulgrim III, Mathilde of Angoulême, who had married Hugh IX of Lusignan, father of Hugh X of Lusignan.
