Comte en Bourgogne, Duc en Provence, Seigneur de Baugy et Seigneur de Perrecy
------------------------------------
Childebrand is described as "germanus" of Charles "Martel" by the Continuator of Fredegar, in the part which Childebrand himself sponsored. There are three possibilities for the precise parentage of Childebrand: (1) he was the illegitimate son of Pépin "le Gros" by an unknown mistress; (2) he was Pépin’s second son by his second [wife] Chalpais; or (3) he was the son of Chalpais by an earlier marriage. Settipani discusses in detail the arguments in favour of each of these three cases. Each case has its defender, but there appears no way of deciding which is the most likely, especially given the uncertain interpretation of relationship terms such as "germanus" in contemporary sources.
Count in Burgundy, Duke in Provence 737/39. A charter dated Apr 754 records a claim by “Fulchardus advocatus...Nivelongo comiti” before “Theoderico comiti” relating to property “in pago Augustidunense in villa Balgiaco...de villa Patriciaco” granted to “Hildebranno” by “Karolus”.
Historian, he was the author of part of the continuations of the chronicle of Fredegar written during the reign of King Pépin (751-768). 1
