Ulla is a name of Scandinavian origin, specifically from Norway and Sweden. It is derived from the Old Norse word 'úll', which means 'wolf'. The name was traditionally given to girls born during the winter months due to its association with the Norse god Odin's wolf, Geri, and Freya's wolf, Freki.
The name Ulla has been popular throughout the past century, with periods of increased popularity around the 1920s and again from the mid-2010s onwards. The highest number of births in a single year was recorded in 2020, with seven occurrences.
