Childebrand I (c. 678 – 743 or 751) was a Frankish duke (dux), son of Pepin of Heristal and Alpaida, and brother of Charles Martel.
He married Emma of Austrasia and was given Burgundy by his father, becoming a duke.
[4][5] He distinguished himself in the expulsion of the Saracens from Francia alongside his brother when he captured Marseille, one of the largest cities still in Umayyad hands.
[3] He was the patron of the continuator of the Chronicle of Fredegar, as was his son Nibelung I or Nivelon.
[2][6] Levellain believe that Childebrand was actually the half-brother of Charles Martel, related through his mother.
