A sizable number of educated Confederates had attended northern colleges before the war, particularly the renowned medical schools and the old Ivy League colleges, and they could also be found at smaller colleges in Pennsylvania such as Dickinson in Carlisle, Franklin and Marshall in Lancaster, Jefferson in Canonsberg, and Lafayette in Easton. I suppose it is less surprising to find them attending schools in border areas like Maryland and even Washington D.C., for instance at Columbian College (now George Washington University).
