The given name Olav (Olaf, Olof, Olaus), the name of Saint Olav, patron of Norway, has also been borne by a number of other Norwegian kings. Conventions of spelling remain quite fluid, with Norwegian predominantly using Olav, and Swedish most often using Olaf or Olof.
In its latinized form Olaf usually comes out as Olaus (with or without an umlaut on the "u"), as is the case for Olaf Petersson (a disciple of Martin Luther and one of the first preachers of the Reformation in Renaissance Sweden), who is also known as Olaus Petri.
There are also Olof-Olaf variants for pre-Christian or early Christian Swedish kings of the 10th century, such as the properly baptized Olof of Sweden.
In general, to find information on men with "Olav/Olaf/Olof/Olaus" as their first name, look up their full names.
