Dygvi, Dyggve or Digne was a Swedish king of the House of Ynglings. He died in bed and never reached Valhalla. Instead he went to Hel, Loki's daughter, who acquired a husband of royal blood:

Dygve the Brave, the mighty king,

It is no hidden secret thing,

Has gone to meet a royal mate,

Riding upon the horse of Fate.

For Loke's daughter in her house

Of Yngve's race would have a spouse;

Therefore the fell-one snatched away

Brave Dygve from the light of day.[1] (http://www.sacred-texts.com/neu/heim/02ynglga.htm)
