Arnardóttirs
Arnardóttir is a common Icelandic feminine given name and surname. As a given name, it is of Old Norse origin and means "daughter of Arni." Arni itself is a diminutive of names containing the element "arn," meaning "eagle." This patronymic naming convention, where surnames are derived from the father's given name, is traditional in Iceland. Therefore, an individual named Arnardóttir has a father named Arni. If the father's name were different, the surname would change accordingly, such as Jónsdóttir for a father named Jón. Icelandic society continues to largely adhere to this patronymic (and sometimes matronymic) system, distinguishing it from many other European countries where surnames are typically inherited through generations. The name Arnardóttir is therefore a direct indicator of a person's paternal lineage within Iceland.
