Vicksburg, Warren county seat 10/7/2004 back to the list We had a chance to make a quick stop at the Vicksburg battleground. We put the name Addy into the datebase of members of the Union and Confederate army. There were 36 members of the Confederate army with the last name, Addy. There were 18 members of the Union army with the last name, Addy. Exactly a 2 to 1 ratio. This is from a complete list of all members of the armies, and not just a list from the siege of Vicksburg.
