I stumbled across a used book in a library clearance sale; “Anthony Wayne: Daring Boy.” It was part of a series called “Childhood of Famous Americans” and I think many were written by an author named Augusta Stevenson. I’d guess they are about 60-70% fictional and definitely reflect a 50s worldview; but I really enjoyed these books as a kid, and now I’m enjoying re-reading the Anthony Wayne one with Cole.
The other one I remember reading was Sam Houston: Boy Chieftain.
The pattern, in those books anyway, is that a boy with promise gets into tough situations, shows pluck, courage, and ingenuity and saves the day; goes on to be Famous American. Sort of a Horatio Alger thing, I guess.
