1 Danish and Norwegian: patronymic from the personal name Olaf, Olav (Old Norse Óláfr, Ólafr, variant Óleifr, earlier Anleifr, from proto-Scandinavian elements meaning ‘ancestor’ + ‘heir’, ‘descendant’). Olaf has always been one of the most common Scandinavian names; it continued to be popular in the Middle Ages, in part as a result of the fame of St. Olaf, King of Norway, who brought Christianity to his country c.1030 . This surname, the second most common in Norway, is also established in England, notably in the Newcastle upon Tyne area.2 German (Ölsen): habitational name from any of several places so named, in Saxony, Brandenburg, and the Rhineland.
