Danish Princes

List of names used for princes of Denmark

Olaf, though sainted and regal in Norway, is slightly oafish here. It is one of those names that has become completely familiar in the U.S. without ever becoming assimilated. Now that he's a comical character in Disney's Frozen, he might get some more attention.
 Olaf's solid Scandinavian history includes various kings of Norway, from the eleventh century St. Olaf (often mentioned by the Betty White character on Golden Girls) to the recent Olaf V.

It may surprise Americans to hear that Ulrik is a fashionable choice elsewhere in the world, as U is the least-used letter for given names in the US. In recent years, Ulrik has been one of the fastest-rising names in Norway.
