Is Patrica Cornwell related to you? Brendan

Dear Bernard, I love your book series! The books are very clever! But, I was wondering if you were related to another very good writer, Patricia Cornwell? I am a student and enjoy history and writing.I was also interested in how you developed an interest in writing about history and eventually made this interest into a career? One last question. I also read The Horatio Hornblower series by C.S. Forester and was wondering if you had read them too? I am looking forward to hearing from you. From an admiring fan, Dan
