Jóhannsdóttir
Jóhannsdóttir is a common Icelandic patronymic surname, meaning "daughter of Jóhann". Jóhann is the Icelandic form of the given name John. As is customary in Iceland, surnames are not fixed family names passed down through generations but are derived from the father's given name, followed by "son" for males or "dóttir" for females. Therefore, multiple individuals named Jóhannsdóttir would not necessarily be closely related unless they shared the same father named Jóhann. This naming convention is a distinguishing feature of Icelandic society. Prominent individuals with this surname exist across various fields in Iceland.
