try and get the full story first.....
Seems the spouse died and the cut a new stone for both the vet AND the spouses names on it.
Granted, it's silly how it was taken care of....but come on....there's more to this...
Supposedly the Veterans' Administration will make a new marker when the writing on the old one can no longer be easily read. However, I don't know how true this is. My great great grandfather, Private William James Stump 128th Indiana Volunteer Infantry, died of typhoid fever after being wounded at the Battle of Kennesaw Mountain (had he stayed with his unit and not have gone to the military hospital in Chattanooga, Tennessee, he may have lived). The marker on his grave in the Chattanooga National Cemetery was barely readable the last time I was there about 7 years ago. Also, his last name was misspelled. I furnished the cemetery officials copies of all the documents and they "promised" to get a new marker. However, I have not been back there to verify that the marker has been replaced. Somehow, my "gut feeling" is that the marker has not been replaced.
