Narrative: When William the Conqueror led his army to victory at the Battle of Hastings in 1066, he not only captured England for himself and his barons, he captured it for a host of French names. Robert, Roger and Richard were numbered among the victors that day, but none were so triumphant as the name of the Conqueror himself.

William has remained a royal name in the United Kingdom for nearly one thousand years. If the current Prince William ascends the throne with that name, he will rule as William V.
