Pepin of Landen
Sigebert was born in 630 as the eldest son of Dagobert I, King of the Franks, and his concubine Ragnetrude. The king recalled and made peace with Saint Amand, who was previously banished for criticizing the king's vices, and asked him to baptize his new-born son. The ceremony was performed at Orléans and Charibert II, Dagobert's half-brother who was King of Aquitaine at the time, was the god-father. Dagobert assigned the education of Sigebert to Pepin of Landen, who was the mayor of the palace in Austrasia under his father Chlotar II, until 629. Pepin took the young Sigebert and moved with him to his domains in Aquitane, where they stayed the next three years.
