Sigurðarson

Sigurðarson is an Icelandic patronymic meaning “son of Sigurð,” and is commonly found as a surname in Icelandic contexts. It does not denote a hereditary family name in the sense used in many other cultures, but identifies the bearer as the child of a father named Sigurð.

Origin and form: Sigurðr is an Old Norse given name formed from the elements sigr, meaning victory, and varðr, meaning guardian. In modern Icelandic, the father's name Sigurður yields the patronymic Sigurðarson, literally “son of Sigurður.”

Usage: In Iceland, naming typically uses a given name followed by a patronymic rather than a fixed surname. A son of Sigurður would be called [Given name] Sigurðarson; a daughter would be [Given name] Sigurðardóttir. Outside Iceland, or in historical records, Sigurðarson may appear as a fixed surname or be anglicized in various ways (for example, as Sigurdsson in some contexts).

Notes: The form reflects Norse naming traditions carried into Icelandic practice and remains common among Icelanders and people of Icelandic descent. It functions as a descriptor of paternal lineage rather than a universal family name, which influences how individuals are indexed and addressed in different cultural contexts.
