I need to check in the Village Cemetery at Edgefield to see if his grave is marked. It is an old, but very active cemetery, in which one of our Civil War Governors, Francis W. Pickens, MGEN (and later U.S. Senator and BGEN, USV in the Spanish-American War) Mathew C. Butler, and a host of othewr notables are buried. And that includes Representative Brooks, who caned Sumner just before the war.
The South Carolina Daughters recently published a twelve volume set of memoirs, letters, and other documents. The Edgefield Chapter was very active in preserving such documents, and one of the recollections in it is a memoir by a young girl who went to the Soldier's home with her mother to nurse the soldiers. I'll try to look it up.
