The King James Bible is also a great place to find names. The Old Testament, especially Genesis, is full of monikers! Just open it to any page and someone is naming a plain, river, mountain or even piles of rocks. A lot of these terms are also English and Greek approximations of Hebrew and Aramaic, and thus have a really nice ancient, eldrirch feel.
