Scholarly research confirms that the surname Olsen originated in the Norse regions of Northern Europe, deriving from the Old Norse personal name Óláfr and, in some interpretations, from the related form Anleifr. Both forms are constructed from elements denoting god and relic, and the latter is believed to have been transmitted northward to Scotland and Ireland through early Scandinavian colonisation.

The name Óláfr itself carries the meaning ancestor’s descendant or heir of the ancestors, making the patronymic surname Olsen a literal identification of son of Olaf. This structure is typical of Scandinavian naming conventions, whereby the suffix -sen indicates paternity. Consequently, the name was first recorded among the scions of men named Olaf, a name that gained considerable popularity across Norway and Denmark in the medieval period, partly owing to the reigns of several kings who bore the name.

In the Christian context of medieval Scandinavia, the cult of St. Olaf, King of Norway who died circa 1015 and was credited with bringing Christianity to his realm, amplified the name’s prestige and spread. Churches dedicated to St. Olaf were abundant, and baptisms often recorded the surname in its patronymic form. The religious significance of the name is therefore evident from the early church registers of regions such as London and Westminster, where the surname appears in documented baptisms and marriages.

Historical records demonstrate the settlement of individuals with this patronymic surname beyond Scandinavia. For example, on 26 September 1677, Bernard Olsen married Martha Willis at St. Katherine by the Tower in London. Later that decade, Mary, the daughter of Bernard and Martha, was christened at St. Dunstan's in Stepney on 26 November 1683. Earlier, in the late thirteenth century, a Charles Olsen was christened at St. Anne Soho in Westminster on 24 November 1294, thereby providing further evidence of the surname’s presence in England during the late medieval period.

The earliest documented Scottish reference to the name appears in the Subsidy Rolls of Worcestershire, where a record of a man titled Robert Olef is dated 1275, during the reign of King Edward I, known as “The Hammer of the Scots”. This instance indicates that the surname, in its varied spellings, was already entrenched in the English administrative records by the late twelfth century.

Modern variations of the surname include Olufsen, Olesen, Ohlsen, Olsson, and Ovesen, reflecting local orthographic practices. The continuity of the patronymic tradition, however, is discernible across all these spelling forms, underscoring the enduring legacy of the name Olsen within the broader Scandinavian diaspora and its integration into the British historical record.
