On Andrew Jackson, who was in my GGG-grandfather's company: "Private Andrew Jackson -- 5-10/62 absent sick; 6/11/63 killed Vicksburg (“Jackson of Co. K killed being shot through the head with a minnie ball.”)

I don't have any info on his burial site.

However, many of those brave Southern Patriots who died in the trenches at Vicksburg were later reinterred in the Confederate section of the huge Vicksburg cemetery -- "Cedar Hill."

He may be buried there, though I don't find his name on any of the cemetery listing at hand.

Wish I could have helped you more! -- Jim Huffman, Picayune, MS
