Hello.
Yes, Lt. Col. Wagner is at rest in the cemetery of St. Michael's Church, Charleston, SC. He has a handsome marker in the rear of the churchyard. I was actually searching for other CSA officers grave sites when I glanced and saw his name. I couldn't believe it. I enjoy very much the hunt of grave sites of Civil War notables -- he was one that I was glad to find. One down, many to go.

Yr Obt Srvt.
