I believe he was in the 56th Alabama and may have joined up in Mississippi.
I believe there was a B. S. Bobo and a Barrum S. Bobo.
Family story: I seem to have this very vague memory of overhearing the "old folks" talking when I was a young child and hearing my grandmother saying something like "mama applied for a pension but papa had deserted".
This seems to make matters worse. Any help will be appreciated.
