Bilichild was a daughter of King Sigebert III and Queen Chimnechild of Burgundy and granddaughter of King Dagobert I and his concubine Ragnétrude.
Children of Bilichild and her husband were Prince Dagobert and King Chilperic II.
While on a hunting trip in the Forest of Lognes, near Livry, in Picardy, Bilichild, along with her husband and her eldest son, the five-year-old Dagobert, were assassinated by a band of dissatisfied Neustrians—Bodilo, Amalbert and Ingobert.
The royal trio was buried in Saint-Germain-des-Prés at Paris,[2] where her tomb and that of Dagobert were discovered in 1645 and pilfered.
Her younger son Daniel was whisked off to a monastery and from there returned forty years thence to lead the Franks as king under the name Chilperic II.
