Ulf is a Norse name of Old Germanic origin, derived from the word "wulf", meaning wolf. It was popular among the Scandinavian Vikings and is still used today in Scandinavia, particularly in Sweden where it's considered one of the oldest recorded names. The name Ulf has been borne by several notable historical figures, including Ulf Jonson, a Swedish nobleman who lived in the 13th century, and Ulf Timmermann, a German-American strongman and circus performer from the late 19th to early 20th centuries. In popular culture, Ulf appears as a character in several works, such as the novel "The Girl with the Dragon Tattoo" by Stieg Larsson, and the film "Kong: Skull Island".
"The name Ulf was given to five babies born in the year 1965."
