Thanks for the information. It appears we were wrong in our initial assumption about the writer of the letters from Bull Run, who was, in fact, John William Bason, brother of Ida Theresa Bason, my wife's great grandmother. John and Ida's parents were Henry Bason and Mary Bason, nee Trollinger, and we are guessing that this Mary may have been the aunt of John T. Trollinger, making him a first cousin of John W. Bason. The latter was also captured at the first Battle of Rappahannock, was released in 1865 and lived on until 1922, when he died aged 84 and was buried in the cemetery of Hawfields Presbyterian Church, NC. If you have any information on the possible link between John T. and Mary Trollinger, I would be very interested.
