الأصل والتاريخ

Patronymic surname meaning 'son of Jon' — see rank 12 entry. In Sweden, Jönsson with umlaut represents a separate orthographic tradition, indicating that the father's name was spelled with the front-rounded vowel characteristic of some regional Swedish dialects. The variant Jönsson is most common in Skane and Smaland, where the umlaut vowel 'o' survived longer in local speech. The fictional character Sickan Jönsson, protagonist of the beloved 'Jönssonligan' crime comedy film series (1980–present), has made Jönsson a culturally iconic name in Sweden.
