Thorgilsson

Thorgilsson is a surname of Scandinavian origin, primarily associated with Icelandic and Norwegian heritage. The name derives from the Old Norse personal name *Þorgnýr*, which combines the elements *þórr* (meaning "Thor," the Norse god of thunder) and *nýr* (meaning "new" or "young"). The suffix *-sson* indicates "son of" in Old Norse, suggesting that individuals bearing this surname are descendants of a man named Þorgnýr.

In Iceland, surnames were not traditionally used until the 20th century. Before then, people were identified by their father’s given name followed by *son* (for males) or *dóttir* (for females). For example, a man named Þorgnýr’s son would have been called Þorgnýrsson. After the adoption of fixed surnames in 1910, many Icelanders adopted patronymic surnames, leading to the modern form *Thorgilsson*.

The surname is relatively rare outside Scandinavia but appears in records from Iceland, Norway, and other countries with historical Norse influence. Notable figures with the surname include historical figures, though no widely recognized public personalities are commonly associated with it today. The name reflects the broader cultural and linguistic legacy of Norse settlement in the North Atlantic region.

Variations of the surname may exist due to regional dialects or spelling changes over time, such as *Thorgnisson* or *Thorgnisson*. As with many patronymic surnames, the spelling can vary slightly depending on historical records and local traditions.
