"From the day of Clovis' marriage the history of France has been bisexual, mingling love and war. Sigebert sent costly presents to Athanagild, Visigothic king of Spain, and askedfor his daughter Burnhilda; Athanagild, fearing the Franks even when they bore gifts, consented; and Brunhilda came to grace the halls of Metz and Reims (566). Chilperic was envious; all that he had was a simple wife, Audovera, and a rough concubine, Fredegunda. He asked Athanagild for Brunhilda's sister; Galswintha came to Soissons, and Chilperic loved her, for she had brought great treasures. But she was older than her sister. Chilperic returned to the arms of Fredegunda..."
Audovera married King Chilperic NEUSTRIA, I, son of King Chlotar FRANKS, I and Queen Ingonde FRANKS. (King Chilperic NEUSTRIA, I was born about 519-539 in , , France and died about 561-584 in Dy, Austrasia, France.)
