Boso III of La Marche
Boso III of La Marche (died 1091), son of Aldebert II and Ponce, was count from 1088. In 1071, in his father's lifetime, he already bore the comital title in Duke William VIII of Aquitaine's following, and he later endowed Le Dorat Abbey.
He was killed in 1091 while besieging Confolens. Married but childless, he was succeeded by his uncle Eudes I over his sister Almodis I's claims.
