"Anya" is the Russian form of Anna, based on the French "Anne" and part of the name "Marianne". Not only that, Marianne was said to have rode a horse through a window into the Imperial Palace to protect Lelouch and Nunnally from being bullied by the other Imperial Wives.

Much like how Anya rescues Lelouch from certain death at the hands of Suzaku in her "horse", the Knightmare Mordred.

I think it's pretty clear Anya = Marianne.

As if the official art didn't all but confirm it already.
