Our Wiser family alive in 1906 and living in Liberty or Chambers County Texas might have read this in the local newspaper.
The "boys of '61." Now there's a phrase I've not heard before. Was it a common refrain?
UPDATE: YES, apparently it was! I just googled it. The free book site, Gutenberg, even has copies available of author Charles Carleton Coffin's book by that same name/phrase. Evidently Mr. Coffin was an embedded reporter with the Union Army.
