ᛝ Ing

 ᛝ [Ing] wæs ærest mid eastdenum ġesewen secgum
oþ he siððan eft ofer wæġ ġewat wæ[ġ]n æfter ran
ðus heardingas ðone hæle nemdun.

ᛝ [Ing] was first seen by men with the East Danes
until he thence back over the wave went, the waggon ran behind,
thus the heardingas the hero named.

The "heardingas" are often said to be the Haddingjar found in Old Norse writings and the Asdingi who are the kings of the Vandals. From *Hazdingōz "sons of the long-haired one"?  In the article 'Helgi Haddingjaskati and his Place in the Old Norse Hero-Legend' (Publications of the Society for the Advancement of Scandinavian Study Vol. 2, No. 2 (March, 1915), pp. 63-78 (16 pages)) A. Leroy Andrews rightly rubbishes Karl Müllenhoff’s theory that there are any comparable German Hartungen:

“Hartnit and his brother are nowhere referred to as Hartunge and Müllenhoff in designating them as such was evidently influenced by the German brother-pair the Harlunge.”

The historic Vandals seem to have come from Vendsyssel in Jutland, which Adam of Bremen (ca. 1075) calls Wendila, and our Ælnoth (ca. 1100) Wendel.  As the Asdingi/Haddingjar were likely to have been their kingly stock, we can see why Saxo Grammaticus in his Gesta Danorum chose to trace the line of the old kings of the Danes back to one "Hadingus".  A. Leroy Andrews "Haddingjaskati meant then "king of the Danes"...".  And we can see why, if "heardingas" is indeed the English evenling to Asdingi/Haddingjar, why the writer of the above verse thought it a good byname for the Danes.
