"Clovis II (633 – 657) is King of Neustria and Burgundy succeeded his father Dagobert I in 639. His brother Sigebert III had been King of Austrasia since 634. He was initially under the regency of his mother Nanthild until her death in her early thirties in 642. Nanthild was probably poisoned or secretly murdered by the nobility, as her death allowed Clovis to fall under the influence of the secular magnates, who reduced the royal power in their own favour; first Aega and then Erchinoald.
Clovis´ wife, Balthild, whose Anglo-Saxon origins are now considered doubtful, was sold into slavery in Gaul. She had been owned by Clovis´ mayor of the palace, Erchinoald, who gave her to him to garner royal favour. She bore him three sons who all became kings after his death. The eldest, Chlothar, succeeded him and his second eldest, Childeric, was placed on the Austrasian throne by Ebroin while Clovis was still alive. The youngest, Theuderic, succeeded Childeric in Neustria and eventually became the sole king of the Franks." - (en.wikipedia.org 04.10.2020)
