Although interested in all aspects of the war, John's main interest lies in the Civil War history of his native Schuylkill County, Pennsylvania, and particularly the 48th Pennsylvania Infantry, a regiment recruited almost entirely from Schuylkill County. John hosts a blog dedicated to the 48th PA, which can be found at: www.48thpennsylvania.blogspot.com
