Ásgeirsson

Ásgeirsson is an Icelandic patronymic surname meaning "son of Ásgeir." In Iceland, most surnames are patronymics generated from the father’s given name rather than fixed family names. The suffix -sson (for sons) indicates paternal lineage, while the corresponding feminine form is -sdóttir, as in Ásgeirsdóttir for a daughter of Ásgeir. Ásgeirsson specifically denotes that the bearer's father was named Ásgeir.

The given name Ásgeir itself comes from Old Norse Ásgeirr, typically analyzed as combining elements meaning "god" or "Æsir" and "spear," yielding a meaning related to a god-spear. Consequently, Ásgeirsson translates roughly to "son of Ásgeir" in contemporary usage.

In daily practice, Icelanders are generally addressed by their first given name, with the patronymic appearing in formal or official contexts to indicate lineage. The use of Ásgeirsson as a family surname is uncommon in Iceland but may occur in historical records or among Icelandic diaspora communities where patronymics have been adapted into inherited surnames.

The feminine form of the name is Ásgeirsdóttir, reflecting the same ancestor. As a surname, Ásgeirsson can be found among Icelandic people and those of Icelandic descent living abroad. In reference works, Ásgeirsson is treated as a patronymic indicating paternal descent rather than a fixed hereditary surname.
