The author of the
Chronicle of Fredegar criticises the king for his loose morals in having "three queens almost simultaneously, as well as several concubines".
[a][26] When
rex Brittanorum Judicael came to Clichy to visit with Dagobert, he opted not to dine with him due to his misgivings with Dagobert's moral choices, instead dining with the king's referendary,
St. Audoen.
[27] Fredegar's chronicle names the three queens,
Nanthild and the otherwise obscure Wulfegundis and Berchildis, but none of the concubines, stating that
a full list of concubines would be too long. In 625/6 Dagobert married Gormatrude, a sister of his father's wife
Sichilde; but the marriage was childless. After divorcing Gormatrude in 629/30 he made
Nanthild, a Saxon servant (
puella) from his personal entourage, his new queen.

Clovis II (b. 634/5) later king of Neustria and Burgundy. Shortly after his marriage to Nanthild, he took a girl called Ragnetrude to his bed, who gave birth to his youngest son,
Sigebert III (b. 630/1) later king of Austrasia.
