Þórdardóttir

Þórdardóttir is a common Icelandic patronymic surname. In Iceland, patronymic surnames are formed by taking the father's given name and adding the suffix "-son" for sons or "-dóttir" for daughters. Therefore, Þórdardóttir literally means "daughter of Þórðar." Þórðar is the genitive form of the Old Norse given name Þórðr, which is derived from the name of the Norse god Thor.

Individuals with the surname Þórdardóttir are not necessarily related by a common ancestor beyond their shared naming convention. This system differs from traditional hereditary surnames found in many other cultures. The use of patronymics is deeply rooted in Scandinavian history and continues to be the primary method of surname assignment in Iceland today.

Examples of individuals with this surname might include prominent figures in Icelandic society, such as politicians, artists, or athletes, but the name itself signifies a familial connection to a father named Þórðr, rather than a distinct lineage. The prevalence of patronymic surnames means that many Icelanders share the same surname without being closely related.
