Wulfhild was born in 1020 as the only legitimate child of King Olaf Haraldsson of Norway and his wife Astrid Olofsdotter of Sweden.
It is not determined whether she followed her father and half-brother on their trip to Kievan Rus' or remained in Sweden with her mother, but she did live in Sweden between the death of her father in 1030 until she returned with her half-brother Magnus to Norway in 1035, when he became king.
Wulfhild is described as a beauty, and is thought to have been greatly respected as the only legitimate child of her father and daughter of a saint.
On 10 November 1042, she was married to Ordulf,[1] son of Bernard II, Duke of Saxony.
Her husband did remain loyal to the alliance, but the information about Wulfhild is limited and nothing is known about any of her opinions.
