Harðarson

Harðarson is a surname of Icelandic origin. It is a patronymic surname, meaning it is derived from the given name of the father. In this case, Harðarson means "son of Hörður" (Harður's son). The name Hörður is a relatively common Icelandic masculine given name. Icelandic surnames typically follow this patronymic system, with the addition of "-son" for sons and "-dóttir" for daughters. The use of patronymics (and sometimes matronymics) is a core aspect of Icelandic naming conventions.
