It's possible there's a typo in the name, or the author might be known by a different name or pseudonym.
To help me find the correct author, could you please provide more information, such as:
* Possible alternative spellings of the name: Are you sure about the spelling? Could it be "Oscar Soriano" or "Gatchalian Soriano" instead?
* Genre of their work: Do you remember what kind of books they wrote? Fiction, non-fiction, poetry?
* Any other details about their work: Do you remember any specific book titles, characters, or themes?
With more information, I might be able to help you find the author you're looking for.
