I am researching Dan Showalter in connection with the Drum Barracks Civil War Museum in Wilmington, CA, as part of a larger project on pro-secessionist activity in California during the Civil War. I came across your posting and would be very much interested in any information you have and especially happy to receive a copy of any photos you may have regarding Col. Showalter. I look forward to hearing from you, realizing that your original posting was some time ago. Many thanks.
