An example is the name of Dutch footballer Jan Vennegoor of Hesselink. According to The Guardian, his name derives from "the 17th century, when two farming families in the Enschede area of the Netherlands intermarried. Both the Vennegoor and Hesselink names carried equal social weight, and so – rather than choose between them – they chose to use both. 'Of' in Dutch translates to 'or', which means that a strict translation of his name reads Jan Vennegoor or Hesselink." Some of these Dutch surnames also survive in South Africa, for example, the rugby player Rohan Janse van Rensburg's surname is Janse van Rensburg, not only van Rensburg (which is itself an existing surname). In addition, it was common for wives to be known by their husband's surname (first) and her original/birth name (second) hyphenated. Nowadays, couples can choose any combination of surnames for official use (although their legal name will remain unchanged). Most prevalent remains for the wife to either use a hyphenated surname or use her original/birth name. Few husbands use a hyphenated surname. All children of a couple need to go by the same surname (either their father's or their mother's); and won't normally have a hyphenated surname. Scandinavia Denmark has a tradition of double surnames originating in the 19th century. This was a result of two naming acts obliging commoners to adopt heritable surnames, passed first for the Duchy of Schleswig in 1771, and then for Denmark proper in 1828. Most people chose their patronymic as their heritable surname, resulting in an overwhelming dominance of a few surnames. To reduce the risk of mistaken identity, many Danes started using their mothers' original/birth names as a heritable middle name (similar to the Russian or Hispanic system), rather than as a second given name (as in the Anglo-Saxon system). One example is three successive prime ministers of Denmark all sharing the same last name, Rasmussen, so they are usually referred to by their middle name: Nyrup, Fogh and Løkke, respectively. Currently, the Danish order of names invariably places the patronymic -sen at the end, regardless of whether that name has been passed down by the father or mother, or adopted through marriage. Unlike the Russian or Hispanic systems, this surname-style middle name is not considered a proper last name in official documents, unless hyphenated into one compound name.
