Glenda --
Wish we had some of that rain over our way! When you have time, someone on this board may be interested in the veteran's dates and anything else on the stone. It would be helpful to know if I've identified his unit correctly.
You mentioned men of the 2nd Arkansas Mounted Rifles and 15th NW Arkansas. There may be folks on the Arkansas message board who want to know about your Confederate ancestors. Please consider taking the time to post that information over there.
