Query: Voltaire references

This is a passionate book that seems to be the sum of everything that Sagan cared about. I've always loved it.Has anyone else figured out the origin of Ellie's name? It's an anglicization of "Arouet" which was Voltaire's original surname. There are several references in "Contact" to Voltaire's writings, especially his "conte philosophique" Micromégas.
