Yes, it was really a migration of what would become Anglo-Norman aristocrats but William did bring 10,000 men with him. There are literally hundreds of very prominant Anglo-Norman families. I can trace one line of descent personally from a Breton knight who arrived with William (many of the "Normans" were actually Bretons) unfortunately one of my ancestors brother's murdered (Saint) Thomas Becket (but as I understand it he thought he was being loyal to the King).
