Despite this assertion, the historian Valenciennes d’Oultreman said he could be a character named Aymon: governor of Ponthieu? Furthermore, the historian Jules Duvivier would rather name an ancient Count of Hainaut: indeed, in the 8th century, portions of territories around the present town belonged to the Leudes, fellows of the Frankish kings to whom they were granted. In the 9th century, the region was occupied by the Vikings who settled there along rivers. Around the year 842 at the time of King Charles the Bald, they were blocked at Valenciennes, as the river became too narrow for their boats. Later, the land at Le Queroy became a freehold belonging to the Episcopal mass at Cambrai and by the name of"Noflus", latinized from "Novem fluctibus". Finally, 1148, the freehold was sold by the Bishop of Cambrai, Nicolas de Chièvres to Count Baldwin IV of Hainaut.
