Tom, absolutely Private William Y. Mooty would have been qualified for getting a Confederate tombstone even though his term was short and he was in the State Guards. There were many in the Georgia State Guards who were taken as prisoners and died at Northern prison camps and many who were killed on the battlefied and died of diseases just like any other soldier.
Ironically I just came back from the National Archives in DC and brought back with me a lot of information about the early Confederate tombstones. There were specific dimensions for the Confederate stones made in 1907 and 1908 paid for by the United States Government in which about 25,000 were made. Since you can't pull the stone out of the ground we will not know its height nor its weight, however we can still get its width. When you get a chance please take a tape measure and measure the width within a 1/16 of an inch. Do so on both tombstones. Any then measure the stones thickness. In 1908 the stones cost the government $2.90 a piece. Among other papers I have a copy of the orginial contract between the government and the Blue Ridge Marble Company. The stones are rather historic in my opinion and the Confederate stones were made from a type of marble called Cherokee Marble. There were several different stone quarries at Nelson, Georgia. The Confederate stones were not made from the highest grade of marble. The highest grade of marble at Nelson, Georgia was used to help build the Lincoln Memorial and used in the West Wing of the White House from what I understand.

Your discovery of widow's getting a Confederate tombstone was new to me. However, what seems to be the same stone by the naked eye may have different results once you measure them. I guess I should have been born in Missouri. Since Private Mooty appears to have died in 1912 I am assuming that the same dimensions in 1907-08 would have been used. I shall post tomorrow on what those dimensions were and your job is to measure them if you get a chance.

Barry also posted some great information on the Nancy Hart's and all of our posters made some valid points in my opinion. I did notice the date of Barry's Post (1861) and Mary could have been one of those women in 1863, although if she was I believe it would have been carried down through the families oral history. George Martin that posted to your reply is an outstanding Civil War author and I had my first chance at browsing at his book a few weeks ago.

I do admire your determination and commitment for finding the truth Tom and some of us may learn something of your future discoveries.
