Oh, so you had already done that? Were you asking for something else then, or did you just happen to do it on your own after making the thread?
If the address is not in Google, then I won't be able to derive the coordinates THROUGH Google - maybe through some other service or website, but I am not knowledgeable on any resources that are guaranteed to have every address in the world in their database (this would be required in order to also get the coordinates).
