I will be glad to tell you about the book. I am writing a biography of the Terrill Family of Bath County, Va. This family contributed two Brigadier Generals to the war - one northern and one southern. George Porterfield married Emily C. C. Terrill, sister of the generals. Because of this connection, there will be a biography of Porterfield included in the book. He is quite an interesting character, and deserves his own story. Thanks for asking.
