Question: Who is Achila Ii's paternal grandfather?
Sentence (from "Achila II"): Because of the oppressive policy of his predecessors towards the Jews and the large Jewish population of Narbonensis and because of what he stood to gain should Roderic be removed, military historian Bernard Bachrach has written that "[t]here is a temptation to conclude that the Muslims, King Achila, and the Jews all joined together, at least temporarily, to overthrow Roderic."
Relevant evidence: No
