MedLands has CHARIBERT King of the Franks, but no son of the same name. Four wives, three daughters (Berta, Berthefledis, and Clotilde) and one son who died in infancy, name, if any , not recorded.
As to Charibert of Neustria, there is only this: "According to Europäische Stammtafeln[514], Chrodbert [I] and his brothers were sons of "Charibert nobilis in Neustria †635". No reference has been found to this person in any of the primary sources so far consulted and it has been decided to omit him until a positive identification can be made." https://fmg.ac/Projects/MedLands/FRANKSMaiordomi.htm
NOTE: Europäische Stammtafeln is an extensive compilation of European family trees, and as such as (un)reliable as any other family trees.
