Brunissende of Foix
Brunissende of Foix (died September 1324), daughter of Roger-Bernard III, Count of Foix, and Margaret, Viscountess of Béarn, married Count Hélie IX of Périgord in 1298 with a dowry of six thousand livres. Widowed in 1311, she ruled the county as regent during the minority of her son Archambaud.
She was widely believed to hold great sway at the new Avignon curia; chroniclers even rumored she was the mistress of Pope Clement V, and she secured rich church benefices for her son Hélie, later an influential cardinal. Her sons Archambaud and Roger-Bernard each became Count of Périgord.
