What is "ansbertus"

Ansbertus or Ansbert, Ausbert was a Frankish Austrasian noble, as well as a Gallo-Roman Senator. He is thought to be the son of Ferreolus, Senator of Narbonne and his wife Saint Dode. This would perhaps make him the great-grandson of Sigimerus (son of Clodius) and his wife, a daughter of Ferreolus Tonantius (a Roman Senator and Praetorian Prefect of Gaul). His wife Billihild was reputed to be a daughter of Charibert I, Merovingian King of Paris, and granddaughter of Chlothar I.

Little of his actual life is known. Published centuries later, the Liber Historiae Francorum states that an Ansbertus married Blithilde (also called Bilichilde), and that she was the daughter of "Lothar the father of Dagobert", and then continues the line to the Pippinids through his son Arnoald and his granddaughter Itta (wife of Pepin of Landen).
