On 10 November 1042, Wulfhild was married to Ordulf, son of Bernard II, Duke of Saxony. This marriage was supposed to strengthen the alliance between Saxony and Denmark; her half-brother expected the support of her consort to strengthen his position in Denmark by fighting the Wends. The marriage ceremony was celebrated in Schleswig during these political negotiations. Her husband did remain loyal to the alliance, but the information about Wulfhild is limited and nothing is known about any of her opinions.

Wulfhild and Ordulf had a son, Magnus, Duke of Saxony.
