Þorgnýrsson

Þorgnýrsson is a common Icelandic patronymic, meaning "son of Þorgnýr". In Iceland, surnames are typically formed by taking the father's given name and adding either "-son" for a son or "-dóttir" for a daughter. Therefore, Þorgnýrsson indicates that the individual's father was named Þorgnýr. This patronymic system is a distinctive feature of Icelandic naming conventions. Individuals with the surname Þorgnýrsson would share the same paternal ancestor named Þorgnýr, but they are not necessarily closely related in the modern sense of a family surname that is inherited. The name Þorgnýr itself is of Old Norse origin, composed of the elements "þorg" (likely related to Thor, the Norse god) and "nýrr" (meaning new). It is a historical given name that has persisted through generations, leading to the prevalence of its patronymic forms. This system allows for a clear genealogical link while also ensuring that each generation has a unique family name based on their father's name.
