I have already posted about the curious double Gerald-Azelma marriages, and it seems that Medieval Lands even says that there is curious wording in the charter that is the only documentation of this one's marriage to Gerald III.

The Genealogica Comitum Guasconiæ names "filiam…Adalmur" as the child of "Astam-Novam", specifying that she was the mother of "Benetricis" who was childless[762]. The primary source which confirms the identity of her first husband has not yet been identified. "Geraldus comes Armaniacensis…cum filio suo primogenito Bernardo" confirmed a donation to Sainte-Marie d’Auch after the death of "istius comitisse…et filie eius Benetricis", desiring "consulatum Fezenciaci", by undated charter[763]. This is the only charter cited by Jaurgain which supposedly confirms Azelma’s second marriage[764]. However, it is a curious document. The wording implies that Comte Géraud confirmed Azelma’s donation because he desired her county, although the confirmation was made after she died. If he had married her, however, he would presumably automatically have been entitled to Fezensac and the stated purpose behind the confirmation would have been pointless. Another factor is that Géraud’s son Bernard is described in the document only as his son not hers.
To many coincidences for my money, and the first part says that her son was childless. I think this one is a false person, and Bernard IV's mother is unknown.
