Guðmundssons

Guðmundssons is an Icelandic patronymic surname. In Icelandic naming tradition, Guðmundsson means “son of Guðmundur,” formed by taking the genitive form of the given name Guðmundur and adding the suffix -sson. Female equivalents use Guðmundsdóttir. Icelandic surnames are typically patronymic rather than fixed family names, so a person’s last name changes across generations to reflect their parent’s given name.

The given name Guðmundur derives from Old Norse Guðmundr, from guð meaning “god” and mundr meaning “protection” or “guardian.” Therefore, Guðmundsson literally denotes descent from a father named Guðmundur rather than indicating a long-standing family lineage.

In everyday usage, Guðmundsson may be used as a surname by individuals in Iceland or among diaspora communities; however, the standard practice remains patronymic, not a stable hereditary surname. Consequently, siblings may have different last names if their parent’s given names differ in the next generation.

In English-language contexts, the form may be rendered as Gudmundsson or Gudmundsson, with diacritics often omitted. The plural form Guðmundssons is uncommon in Iceland but can appear in encyclopedic or genealogical references when referring to multiple individuals bearing the surname outside Iceland.

Notable individuals bearing the name exist across various spheres of Icelandic public life, including politics, sports, and academia. The surname signals its patronymic origin rather than a fixed family lineage. See also Icelandic naming customs and the given name Guðmundur for related information.
