Ingerman (Ingram, Enguerrand) (c. 750-818), was a Frankish noble and Count of Hesbaye, son of a brother of Saint Chrodegang, the Bishop of Metz and therefore grandson of Sigramnus of Hesbaye.
Ingerman and Rotrude had one daughter: There seems to be only one primary source directly mentioning Ingoram.
In a medieval life story of Emperor Louis the Pious, by Thegan of Trier, Louis's wife Ermengarde is said to be a daughter of the noble duke Ingorammus, who was son of a brother of Hruotgangi "sancti pontificis",[2] or in other words Saint Chrodegang.
Chrodegang in turn was named in one medieval record as having parents who were nobles from Hasbania (Hesbaye).
[3] Paul the Deacon identified the parents of Chrodegang as Sigram and Landrada.
