They were described in Wikipedia as nephews (one reference - brothers) also, based on:

6. Procopius, De Bellus III.9.5. Translated by H.B. Dewing, Procopius (Cambridge: Loeb Classical Library, 1979), vol. 2 p. 153p

Huneric, King of the Vandals & Alans (father of Hilderic) Is described as having one repudiated wife, no children, and one son by wife Eudoxia Minor

So, how were these men actually related? The repudiated Goth wife could have had siblings who had sons?
