Boso III of Périgord

Boso III (c. 990–1031/1044), count of Périgord, was probably a younger son of Boso II. He succeeded his brother Hélie II around 1033, possibly after ruling at his side as co-count.

His marriage to Aina brought him the seigneuries of Montignac and Grignols. Their son Adalbert II, who died in 1072 or 1073, succeeded him as count of Périgord.
