Robert of Torigny records the death in 1160 of "Constantia regina Franciæ" while giving birth to a daughter. Ralph de Diceto´s Ymagines Historiarum record in 1160 that “regina Francorum filia Athelfunsi imperatoris Hispaniarum” died while giving birth to a daughter who survived (“incolumi filia”). The Chronicle of Ralph of Coggeshall records that King Louis VII had "aliam filiam de Constantia…Adelaidis", her mother dying while giving birth to her. The Historia Gloriosi Regis Ludovici VII records that the king had "unam filiam de Constantia regina…Adelaidis", stating that her mother died in giving birth. The Chronicle of Alberic de Trois-Fontaines names "reginam Margaretam Anglie et comitissam Aaliz" as childen of King Louis VII & his second wife, specifying that Alix married "Guilelmus comes de Pontivo". The De Rebus Hispaniæ of Rodericus Ximenes names "Adelodis" as the daughter of "Ludovico Regi Francorum" and his wife "Elisabeth" (error for Constantia), specifying that she married "Comitis de Pontivo".
There is some confusion between this daughter and King Louis VII's supposed daughter Alix by his third wife. Roger of Hoveden records that the betrothal of King Louis's daughter to Richard of England was first proposed in 1161, when Richard's older brother Henry was betrothed to her sister Marguerite. Chronologically, this can only refer to the king's daughter by his second marriage. This appears to be confirmed by the Chronicle of Gervase which records the betrothal in 1169 of "Ricardus…filius regis Anglæ" and "filiam regis Franciæ quam habuit de filia regis Hispanorum".
Ctss de Bourges 1174, as her dowry. Benedict of Peterborough records the betrothal "XI Kal Oct 1177" of "rex Anglie…Ricardus comes Pictaviæ filius eius" and "regi Franciæ…filiam" as part of the peace agreement between the two kings. It is assumed that this refers to the same daughter, although the primary source which confirms this beyond doubt has not yet been identified. If this is correct, she was presumably the same daughter who later married the Comte de Ponthieu. Until further information comes to light, it is assumed that Alix/Adelaide who was betrothed to Richard, and who later married the Comte de Ponthieu, was the daughter who was born in 1160, and that King Louis had no daughter of this name by his third marriage. Alix was brought up in England after her betrothal. Benedict of Peterborough records that the betrothal of "Alesia soror eius [Philippi regis Franciæ]" and Richard was renewed in 1189, commenting that the king of England "in custodia habet". Richard refused the marriage after his accession to the throne. Kerrebrouck states that King Richard arranged her betrothal to his younger brother John in early 1193, but the primary source which confirms this information has not been identified.
She returned to France in Aug 1195. Ctss d'Eu, Dame d’Arques in 1195, as her dowry for her marriage.
