Etymology
Rudolph comes from an old Germanic given name built from elements meaning “fame” and “wolf,” usually explained as Hrod- plus wulf. In medieval Latin and later vernacular forms, the name appears in many spellings, including Rudolf, Rodolf, Rolf, and related forms. As a surname, it often began as a patronymic, identifying someone as the son or descendant of a man named Rudolph or one of its shorter forms.
History
The name was especially common in German-speaking areas and also entered English records through continental and Scandinavian influence. Historical surname writers note that shorter forms such as Rolf or Rolph could stand for Rudolph in some contexts, which helped create a wide family of related surnames. The surname also spread into Dutch and North American usage through immigration.
