Diane, thank you for the pointers. Yes, I knew about the "13th Cavalry" designation as well as the "8th", and it can be confusing at times. I'm also familiar with the websites you pointed me to. I've done a great deal of research on this regiment as well, and would be very interested in exchanging notes. Send me a personal email message to mlacy@fuse.net and let me know who your ancestor was!
