- child (-after 772): The evidence for the existence of this second child is provided by the Annales Lobienses which record his mother's departure to Italy "cum duobus filiis" after her husband died. Einhard also records that "Karlomannus frater [Karoli]…uxor eius et filii" went to Italy after Carloman died. Although he does not specify how many children were involved, there was presumably insufficient time between Carloman's marriage and his death for his wife to have given birth to more than two children. There is no indication of the sex of this second child.
