Charles thereupon repudiated his Lombard wife (Bertha or Desiderata) and married in 77 1 a princess of the Alamanni named Hildegarde.
At Easter 781, Carloman, his second son by Hildegarde, was renamed Pippin and crowned king of Italy by Pope Adrian, and his youngest son Louis was crowned king of Aquitaine; but no mention was made at the time of his eldest son Charles, who was doubtless intended to be king of the Franks.
In 783 the king, having lost his wife Hildegarde, married Fastrada, the daughter of a Frankish count named Radolf; and in the same year his mother Bertha died.
The Benedictine abbey of Kempten, said to have been founded in 773 by Hildegarde, the wife of Charlemagne, was an important house.
Elizabeth having died in 1000, Fulk married Hildegarde of Lorraine, by whom he had a son, Geoffrey Martel, and a daughter Ermengarde, who married Geoffrey, count of Gatinais, and was the mother of Geoffrey "le Barbu" (the Bearded) and of Fulk "le Rechin" (see ANJou).
