The Wulfings, Wylfings or Ylfings was a powerful clan in Beowulf, Widsith and in the Norse sagas. While the poet of Beowulf does not locate the Wulfings geographically, Scandinavian sources define the Ylfings as the ruling clan of the Eastern Geats.

The Wuffingas, Uffingas or Wiffings were the ruling dynasty of East Anglia, the long-lived Anglo-Saxon kingdom which today includes the English counties of Norfolk and Suffolk. The Wuffingas took their name from Wuffa, an early East Anglian king. Nothing is known of the members of the dynasty before Rædwald, who ruled from about 599 to c.624. The Viking invasions of the 9th century and Dissolution of the monasteries in the 16th century both led to the destruction of documents relating to the rule of the Wuffingas.
