"Vilelmus quoque vicecomes Massilie et uxor eius Stephana necnon filii illorum Poncius videl, episcopus atque fratres sui Vilelmus iuvenis et Aicardus sive Josfredus, Stephanus quoque atque Bertrannus necnon et Petrus" signed a charter dated 1039. The primary source which confirms her origin has not yet been identified. "Willelmus et uxor mea Stephana et filii mei Poncius episcopi, Willelmus atque Aicardus et Gaufredus et Bertrannus et Petrus" signed a charter dated 13 Apr 1045. "Gauzfredus marchio sive comes Provincie" consented to the donation by "Guillelmus vicecomes Massiliensis et uxor mea Stephana et filii mei…Stephanus et Bertrannus et Petrus" to Saint-Victor de Marseille by charter dated 1045. "Petrus Wilelmi condam vicecomitis Massiliensis filius et mater mea domna Stephana et uxor mea…Theucia" donated property to Saint-Victor de Marseille by charter dated 1055.
Her parentage is unknown. Szabolcs de Vajay states that “il reste établi qu’elle appartenait au clan des Baux, étant la fille de Geoffroy seigneur de Rians”. If that is correct, she was Etiennette, daughter of Geoffroi de Rians & his wife Scocia ---. Szabolcs de Vajay cites numerous sources supposedly in support of his statement, but none of them confirms his supposition. He says that this parentage would explain the family relationships between Bertrand Comte de Provence (son of her supposed daughter Etiennette [Douce]) and Aicard de Marseille Archbishop of Arles and Rostain de Fos Archbishop of Aix. The former was the son of the supposed older half-brother of Etiennette [Douce], so the parentage of the mother of Etiennette [Douce] is irrelevant. In the case of Archbishop Rostain de Fos, the reconstruction of the Fos family shown in this document suggests that their relationship with the Baux family may have been through the wife of the archbishop’s brother which, if correct, would also indicate that it was not relevant in determining the family origin of the second wife of Guillaume [II] Vicomte de Marseille. It is suggested that the indications provided by Szabolcs de Vajay are insufficiently precise to provide a sound basis for speculating on the parentage of Vicomte Guillaume [II]’s second wife and that the affiliation which he suggests is far from “établie”, using his word. 1
