Elias II of Périgord
Hélie II, count of Périgord, was a son of Boso II. When Boso died, the two counties were meant to pass to his nephew Bernard, but William V of Aquitaine kept La Marche for Bernard and gave Périgord to the under-age Hélie, opening the line that held Périgord for four centuries.
He married Adèle and left sons including Aldebert II. He last appears in a papal letter of 1031 and probably died soon afterwards.
