Boso I, Count of La Marche
The Chronicle of Saint-Maixent records Boso, called the Old, as the son of Sulpice. Around 950 he held the Limousin frontier march, building the castle of Bellac as its seat, and is regarded as the first count of La Marche.
Through his marriage to Emma of Périgord he also succeeded to the county of Périgord. From about 968 he warred with Géraud of Limoges and died soon after, dividing his lands among his three eldest sons, Hélie, Adalbert and Boso.
