It's possible:
* The name is misspelled: Perhaps a slight variation in spelling is correct.
* The author is less well-known: It's possible the author is not widely published or has chosen a pseudonym.
* The author has a different name: It's possible they publish under a different name.
To find more information, you could try:
* Searching for variations of the name: Try searching for "William Kable", "Sanderson Kable", or variations of both.
* Searching for specific titles: If you know any titles they might have written, use those in your search.
* Checking author databases: Sites like Goodreads, LibraryThing, or WorldCat can help you find information about authors and their works.
