Hugues-Renaud was named Count of Tonnerre and Bar-sur-Seine after his mother Azeka died. When he chose to become a priest, he ceded his title to Tonnerre to his cousin Ermengarde de Tonnerre, wife of Guillaume I de Nevers, count of Nevers and Auxerre. He ceded his title of Count of Bar-sur-Seine to his sister Eustachie de Tonnerre and her husband Gautier I de Brienne, Count of Brienne.
