You are correct, but the poster to whom I was responding identified Normans specifically and appeared to conflate them lineage with the rest of the other tribes which formed France.
For a time Britain considered portions of continental France including Anjou and Brittany (a semi-autonomous region on the larger land mass) to be under English rule in part due to the fact that Vikings were thrown out of Brittany by the Anglo-Saxons. Calais was in fact Britain's last foothold on continental France.
FReegards!
William of Normandy and his descendants continued to be Dukes of Normandy (until King John lost it to Philip II). Henry II, by marrying Eleanor of Aquitaine, was lord of more of France than Louis VII was.
