Hugh, Son of Charlemagne

Hugh (802–844) was the illegitimate son of Charlemagne and his concubine Regina, with whom he had one other son: Bishop Drogo of Metz (801–855).

Hugh was the abbot of several abbacies: Saint-Quentin (822–823), Lobbes (836), and Saint-Bertin (836). In 834, he was made archchancellor of the Holy Roman Empire by Louis the Pious, his half-brother.

He is sometimes confused with Hugh the Abbot, resulting in the erroneous claim that he had a daughter, Petronilla (born 825, date of death unknown), who married Tertullus of Anjou, the father of Ingelger. This Petronilla was actually a kinswoman of the other Hugh.
