When I was young there were several Civil War veterans still alive. I can remember there being 3. When Uncle Bill Lundy died, there was still 2 left but I think recent research has shown both of them were fakes.
If so, Bill Lundy of Crestview, Florida was the last one.
Funny thing was that so many of the old men took on a new young wife
who were attracted by the on-going widow’s pension.
There are several of those back in my and my wife’s lineage.
