It's possible that:
* The name is misspelled. Perhaps it's "Barry McCarthy" or "Barry Mc Carthy."
* The author is relatively unknown. If this is the case, you might find more information through a specialized literary search or by asking in online forums dedicated to specific genres or literary communities.
Please double-check the spelling and provide more context if you can (e.g., genre, time period) to help me find the author you're looking for.
