Question: Who is Achila Ii's paternal grandfather?
Sentence (from "Achila II"): Because the narrative sources, the numismatics, and the regnal lists all confirm the reign of Roderic during the same years as Achila, it is almost doubtless that the two were kings in opposition to each other following Roderic's coup, which may have resulted either in or from the death of the previous king, Wittiza.
