Helgi (Skjoldung)

According to the Hrolfs saga Kraka, Helgi was a King of Denmark. The saga also made him the son of Halfdan, the brother of Hroar (Old English Hrothgar), and the father of Hrolf Kraki and Skuld.

Of the two, Helgi was the more daring than his brother, although he was younger than Hroar. They managed to escape capture and assassination by their uncle Frodi, who had murdered their father and usurped the throne. With the murder of their father, they were forced to hide with Vifil, and then with their sister Signy, wife of Jarl Saevil (jarl is actually a title, like earl).

In the Old English Beowulf, Helgi was called Helga. He was the son of Healfdene (Halfdan), and brother of Heorogar, Hrothgar (or Hroðgar, Old Norse Hroar) and an unnamed sister. Helga (Helgi) was the father of Hrothulf (Hrolf Kraki).
