I think there are still a handful of Civil War widows out there.
I remember reading a story in the newspaper about two years ago that the last person receiving veterans benefits directly from the Civil War had just died.
Seems that a soldier who had fought in the Civil War was about 81 when he married a 17 year old girl around 1918.
He died soon after but she was entitled to the benefits that go to the wife of a Civil War soldier.
She eventually passed away around 2003 at age 105 or so, but was the last person in America still receiving benefits DIRECTLY from civil war action.
