Tibors was the daughter of Guilhem d'Omelas and Tibors d'Aurenga, who brought her husband the castle of Sarenom, probably Sérignan-du-Comtat in Provence or perhaps Sérignan in the Roussillon.
In 1096, the Comtat was part of the Margraviate of Provence that was inherited by Raymond IV, Count of Toulouse from William Bertrand of Provence.
Over many years, he also acted as artistic director of the Côte Languedocienne festival, a festival that he set up in Sérignan.
