Hugh, son of Charlemagne
From Wikipedia, the free encyclopedia
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 had a daughter, Petronilla (b. 825), who married Tertullus of Anjou, the father of Ingelger.[1]
