It's possible:
* The name is misspelled. Perhaps a slight variation of the name exists (e.g., "Osborn" instead of "Osmaston"). Could you double-check the spelling?
* The author is relatively unknown. There might be a less famous author with that name who has published works, but their publications might be niche or unavailable online.
* The author is a pseudonym. Some authors use pen names, making it difficult to find them under their real name.
To find more information, it would be helpful to know:
* Any other details about the author or their work: Do you know anything about the genre they write in, the approximate date of publication, or any specific titles?
* Where you encountered this name: Was it mentioned in a book, article, or other source? Knowing the context might provide more clues.
