Ingerman, or Ingram was a Frank and count of Hesbaye. His family is known as Robertians. His family line is not entirely sure, but he was probably the son of a Frank named Rodbert. Robert of Hesbaye and Cancor, founder of the Lorsch Abbey were probably his brothers. Landrada, mother of Chrodegang, Archbishop of Metz and first abbot of the Lorsch Abbey, was probably his sister.
Ingerman's daughter is certainly Ermengarde. She married into the Frankish royal family, the Carolingians and was the first wife of King Louis the Pious.
