Need to correct this; another living Civil War widow has been discovered.
Maudie Celia Hopkins, now 89, married 87-year-old Civil War veteran William Cantrell in 1934. Interesting historical trivia, but apparently he didn’t talk about the war very much to her. So there’s not much living testimony to glean from.
It does say something about the economic hardship of the times, however, that a 19 year-old female would marry an 87 year-old man.
