So one thing I've discovered about myself since I've started DMing is that I suck absolute balls at naming anything. And I've found it a lot more easy to just rip a name from the forgotten realms setting and use it for something else in my setting, or reusing that name just flavoring the entity in question to different, but just a little bit familiar.
