Wulfram was born in the diocese of Meaux, at "Mauraliacus", an insecurely identified place near Fontainebleau, probably Milly-la-Forêt, Essonne. He was the son of a certain Fulbert, a knight attached to the court of Dagobert I, king of the Franks. King Dagobert's kingdom was divided on his death, and it was close to the court of his partial successor, Clovis II, king of Neustria and Burgundy that Wulfram is likely to have been born a little after Dagobert had died in 639.
