Some Swedes will be delighted to learn that not only was there a historical d'Artagnan, but also a real life cardinal named Mazarin. But I have yet to find a historical person named Loranga.

There were in fact two Mazarin cardinals. The one people know about, who happened to be one of the major statesmen in Europe at the time, and his brother who was notoriously useless.
