Jane, South, and Civil War are all proper nouns in this context and should be capitalized.
South is not always a proper noun, but since we're talking about the South as a specific geographic area and not south, the cardinal direction, it is. Because it is the South, it's a proper noun.
The same goes for Civil War. There are other civil wars, but because this refers to, "the Civil War," it means a specific one.
