What is "wiglaf"

Wiglaf ( Old English Wīġlāf pronunciation: ) is a character in the Anglo-Saxon epic poem Beowulf. He is the son of Weohstan, a Swede of the Wægmunding clan who had entered the service of Beowulf, king of the Geats. Wiglaf is called Scylfing as a metonym for Swede, as the Scylfings were the ruling Swedish clan. While in the service of the Scylfing Onela, king of the Swedes, Weohstan killed the rebel prince Eanmund and took his sword as a trophy; Wiglaf later inherited it. Weohstan belonged to the clan of the Wægmundings, the same clan Beowulf's father Ecgþeow belonged to; so Wiglaf is Beowulf's distant cousin, and his only living relative at the time of Beowulf's death.
