Note 57 — The First Lay of Helgi Hundingsbane
Henry Adams Bellows translation
Yngvi: one of the sons of Halfdan the Old, and traditional ancestor of the Ynglings, with whom the Ylfings seem to have been confused (cf. Hyndluljoth, 11 and note). The confusion between the Ylfings (or Ynglings) and Volsungs was carried far enough so that Sigurth himself is once called a descendant of Yngvi (Reginsmol, 14). Gering identifies the name of Yngvi with the god Freyr, but the Volsungs certainly claimed descent from Othin, not Freyr, and there is nothing to indicate that Helgi in the Danish tradition was supposed to be descended from Freyr, whereas his descent from Yngvi Halfdansson fits well with the rest of his story. However, cf. Sigurtharkvitha en skamma, 24 and note.
