Thanks for all the help. I am tracking two men who were in Company D, 2nd Mississippi Infantry. William B. Houston I now know was killed in action, probably in the rail road cut at Gettysburg on the first day. The second is the center of my current project. His name is Joseph A. Houston who according to information provided by ancestors was born in 1850 - which means he was 13 at the time of Gettysburg. Furthermore, I know that Joseph was captured at Gettysburg on July 1, and kept at Fort Delaware until the end of the war. I know that many drummer boys or youngsters too young to be exchanged were kept at Fort Delaware. However, there is much we do not know and are now discovering. Joseph is Buried in Arkansas, exact location unknown at the moment, but I do know his stone is not marked, which is the purpose of this project.
