Adalbert I, Count of La Marche

Adalbert I (c. 955–997), second son of Boso the Old of La Marche, was captured with his brother Hélie I by Guy I of Limoges in 974. Released around 977, he married Guy's sister Almodis and was recognised as count in La Marche in 988; he added Périgord after Hélie's death.

In 995 he and Boso II warred against William V of Aquitaine. He was killed by an arrow at the siege of Gençay in 997 and buried at Charroux.
