Evidently Hugh II was the half brother of Guy, who became the bishop of Amiens; Fulk, who became the abbot of Forest l' Abbaye; and Robert.

Bertrand succeeded his father as Count of Toulouse in 1105, and in 1108, he set out for Outremer to claim his father's rights as Count of Tripoli.
Helie accompanied him on this expedition, which resulted in the capture of Tripoli in 1109; shortly after, their nephew, William-Jordan died of wounds, giving Bertrand an undisputed claim to Tripoli.
Bertrand died in 1112, and Pons succeeded him in Tripoli.
Helie returned to France, where she married William III of Ponthieu in 1115.
