The Danish surname Olsen, also found in Norway, is of patronymic origin meaning "son of Olof or Ole". The personal name is derived from an Old Norse personal name composed of the elements anu meaning “ancestor “ and  leifr meaning “heir, or descendant.”  St Olaf, King of Norway (995–1030), aided the spread of Christianity in his kingdom. This surname, the second most common in Norway, is also established in England, notably in the Newcastle upon Tyne area.
