Acfred, Duke of Aquitaine
Acfred (died 927) was briefly Count of Auvergne and Duke of Aquitaine between 926 and his death, succeeding his brother William II. Acfred was the youngest son of the count Acfred I of Carcassonne and Adelinda, sister of William I of Aquitaine. He was the last direct heir of his house. His title of "duke" only appears in a posthumous charter of 928.
