The National Museum of Civil War Medicine has a tremendous amount of information that's been compiled on wartime physicians on both sides of the conflict. Their website <http://www.civilwarmed.org/> has a number of ways to contact them with inquiries. I've personally had a great many very satisfactory exchanges with Dr. Terry Hambrecht there in the past.

Best of luck to you in your research.
