Jay --

You're being overly kind. If you do anything long enough, you're in danger of becoming an 'expert'. Prior to the advent of the internet I was routinely told that only a few real nuts would really want this kind of detail, and time spent reading Confederate service files &c was a huge waste of time.

One person's useless junk is somebody else's treasure.

On a different topic, if you have anything on your ancestor's service in the Tennessee Valley, I'd be interested.
