Adalbert III of Périgord

Adalbert III (c. 1065–1116) was a son of Count Adalbert II Cadoirac of Périgord. After his brother Hélie III died in 1101 or 1104, he ruled the county jointly with Hélie’s sons: his nephew Guillaume III Talleyrand until 1115, then briefly Hélie Rudel in 1116.

Of his own sons, Boson IV later became count; Audebert held the lordship of Puyguilhem; and Raymond became bishop of Périgueux and later archbishop of Bordeaux.
