The Chronicle of St Bénigne de Dijon records an undated charter of "Manasses comes" witnessed by "Walo filius eius et Manasses comes iunior". Although undated, it appears among other charters of the early years of the 10th century. If this is the correct dating, it is unlikely that it refers to Manassès (died after 925) as his sons would at the time have probably been too young to have confirmed charters. In addition, if the donation did refer to Manassès (died after 925) it is unclear why Walo and Manassès would have confirmed but not their brothers Hervé and Giselbert. The conclusion is therefore that the donation relates to the father of Manassès, who has otherwise not been identified. This interpretation appears supported by the Chronicle of Alberic de Trois-Fontaines which in 906 names "comes Manasses Divionensi", specifying that "Walo et alterius Manasses comes iunior" were his sons, although it is recognised that this source is not always chronologically and factually reliable.
Comte de Dijon. A charter dated 912 names "venerabili comite domno Manasse" as present at a judgment in an ecclesiastical court at Dijon by Garnier Bishop of Langres. The word "venerabili" suggests that this document may refer to Manassès [I] rather than his son Manassès [II], although this is not without doubt. 1
