In Scandinavia family names often originate from a patronymic. In Sweden, the patronymic ending is -son, e.g. Karlsson ("Karl's son"). Later on, people from the Scandinavian middle classes, particularly artisans and town dwellers, adopted surnames in a similar fashion to that of the gentry. Family names joining two elements from nature such as the Swedish Bergman ("mountain man"), Holmberg ("island mountain"), Lindgren ("linden branch"), Sandström ("sand stream") and Åkerlund ("field grove") were quite frequent and remain common today.
Another source of surnames in Sweden was the Army, which from the mid-late 17th century was organised as a militia where a number of farms were grouped together and then supported a soldier with a small cottage and piece of land. The soldiers were often given names either describing their character (eg Modig (brave), Skarp (sharp) or Snygg (handsome)), weapons (eg Sabel (sabre), Lans (lance) or Sköld (shield)) or names joining two elements from nature as above. The name often followed the cottage, not the actual soldier. These soldiers' names became very common.
Before AD. 1901 släktnamnsförordningen (Family name regulation act) in Sweden the patronymic was the most widely used instead of a surname.
 Surnames amongst the Swedish gentry
Surnames in Sweden can be traced to the 15th century where they were first used by the Gentry (Frälse) i.e. priests and nobles. The names of these were usually in Swedish, Latin, German or Greek.
The adoption of Latin names was first used by the Catholic clergy in the 15th century. The given name was preceded by Herr (Sir), like Herr Lars, Herr Olof, Herr Hans followed by Latinized form of patronymic names, e.g. Lars Petersson, Latinized as Laurentius Petri. Starting form the time of the Reformation, the Latinized form of their birthplace (Laurentius Petri Gothus, -from Östergötland) became a common naming practice for the clergy. The Swedish family Benzelius was derived from Bentseby (Bentse village) in Luleå the birthplace of Ericus Henrici Benzelius Bothniensis who was the first to adopt the family name. In the example of the Retzius surname was from the lake Ressen, near to the Odensvi parish vicarage in Västervik. Later merchants and other social groups, discarded the formerly used family names (such as patronymic surnames) and adopted high sounding Latin surnames which conjured an image of an old family pedigree.
Another subsequent practice was the use of the Greek language with the ending with "ander", the Greek word for man, (ex. Micrander, Mennander). The use of surnames was still quite uncommon in the 17th century among the nobility and the educated class. Furthermore, the concept of hereditary surnames was also limited to a few families.
When a family was ennobled, it was usually given a name - just as lordships of England and other Western European countries. In the 17th and 18th centuries, the surname was only rarely the original family name of the ennobled; usually, a more imposing new name was chosen. This was a period which produced a myriad of two-word Swedish-language family names for the nobility (very favored prefixes were Adler- (German for eagle), Ehren- (ära, Swedish for honou), Silfver. (silver) and Gyllen- (Swedish for golden or gilded). The regular difference with Britain was that it became the new surname of the whole house, and the old surname was dropped altogether. The ennoblement (in 1632) of Peder Joenson is a case in point, where the use of the old surname was discontinued and thus after the ennoblement Peder Gyllensvärd came into use. An illustration of the old name having an addition to it can be seen the ennoblement of the brothers Johan Henrik Lang and Lars Adam Lang (in 1772) taking the surname Langenskjöld.
