It's possible that:
* The name is a pseudonym. There might be an author who uses "White Eagle" as a pen name.
* You might be thinking of a different name. It's possible you are misremembering the author's name, or there's a slight variation in spelling.
* The author is not widely known. If "White Eagle" is a newer author or writes in a niche genre, they may not be listed in major databases.
To help me identify the author you're thinking of, could you please tell me more about the context?
* What kind of book did they write? (genre, subject matter)
* Do you remember any details about the book? (title, characters, plot)
* Where did you encounter this name? (website, social media, book store)
With more information, I might be able to help you track down the author you're looking for.
