It's possible that:
* The name is misspelled: Could it be a variation like Edward Angevine, Angevine Edward, or something similar?
* The author is less known: Perhaps they have published under a different name or their work is in a niche genre.
* The author is new: Maybe they are an emerging writer with limited published works.
To help identify the author, could you provide more context? For example:
* What kind of books do you think they might have written? (Genre, subject matter)
* Do you know any other details about them? (Time period, nationality, etc.)
* Have you seen any specific book titles or quotes attributed to them?
With more information, I might be able to track down the author you're looking for!
