* The name is misspelled. Could you double-check the spelling?
* The author is less well-known. Perhaps you could provide more context, like the genre of their writing, any specific works you know of, or when they were active.
* You're thinking of a different person. It's possible you're confusing them with a different author.
If you could provide more details, I might be able to help you find the author you're looking for.
