Keith, it's sorta a long story. My ancestor was a nurse in the Civil War. I was looking for information on Thomas J. Jackson's sister Laura being a Union nurse. Also I'm a student of the Boer War. A guy named Byron Farwell writes on the Boer War. A friend of mine told me about a book he had written on Jackson that mention his Unionist sister. I book the book and found the information on the arm.
