Nónsdóttir
Nónsdóttir is a patronymic surname of Old Norse origin. In the Old Norse naming system, the suffix "-dóttir" indicated "daughter of." Therefore, Nónsdóttir literally translates to "daughter of Nón." This system was common in medieval Scandinavia and is still reflected in some modern Icelandic surnames. Individuals with the surname Nónsdóttir would have originally been identified as the daughter of a father whose given name was Nón. While the practice of using patronymic surnames has largely faded in many parts of Scandinavia, Iceland retains a strong tradition of patronymics, with many Icelanders bearing surnames derived from their father's or mother's given name. The name Nón itself is of Old Norse origin, though its precise meaning is not definitively established, with interpretations sometimes suggesting a connection to night or a specific deity. As a surname, Nónsdóttir is therefore a historical linguistic marker, connecting individuals to their paternal lineage through a naming convention that was once widespread across the Nordic region.
