Wulgrin III of Angoulême, also known as Wulgrin Taillefer II, inherited the title of Count of Angoulême and its territories from his father,
William VI of Angoulême, in 1179.[1]
^
Historians have given a variety of dates for Wulgrin's ascension to the countship. Watson (453) gives it as 1179, backed up by charter evidence (353–62).
Geoffrey of Vigeois' chronicle (325–26) also declares William VI to have died in 1179 and Wulgrin III to have ruled for only two years.
