I found a Calvin Brumbelow, a Sgt in I Company, 4th Georgia Calvary, who died in the Rock Island, IL Federal prison on Feb. 16, 1864. He is apparently buried there in grave #560. This company was from Whitfield County, GA, and known as Galt Volunteers. The location is right for my Calvin Brumlow. Also information is that his wife may have been a Amanda Williams, not Millirons. Any help appreciated. Does anyone have a list of the children of Calvin & Amanda and source?
