does anybody know surtalogi and hroptatyr's eng voice actors?

I lovee the 5 sinners and I really wanna know who voices these two in the eng dub. We already know Rerir's (Blythe Melin), Rhinedottir's (Ivy Dupler) and Vedrfolnir's (David Cui Cui) but what about the other two? Any idea or speculations?
