Nordahl is a Scandinavian given name of Norse origin, derived from the Old Norse elements 'norðr' meaning 'north' and 'álfr' meaning 'elf'. This uncommon name has been used in Norway and Sweden for centuries but remains relatively unknown outside Scandinavia. It's often associated with the Norwegian writer and Nobel laureate, Knut Hamsun, whose birth name was Knud Peder Nordahl Lie.
"The name Nordahl was quite popular in 1917 with five births that year."
