Köldússon
Köldússon is an Icelandic surname. The name is derived from the Old Norse words "kaldr," meaning cold, and "son," meaning son. Therefore, Köldússon literally translates to "son of the cold one." Surnames in Iceland have historically been patronymic, meaning they are formed from the father's given name. In this case, it indicates that the father's name, or perhaps a descriptive epithet, was related to the concept of "cold." Like most Icelandic surnames, Köldússon would indicate a male ancestor. A female descendant would typically have a name ending in "-dóttir" (daughter). The prevalence of this surname is likely tied to specific family lineages within Iceland. While not as common as some other Icelandic surnames, it is still recognizable within the country. The cultural context of Iceland, with its significant glaciers and cold climate, may have influenced the adoption of such descriptive names in the past.
