Rose,
There is an Evening Shade Church south of Fort Smith in the Ouachita region. I don't know if the name has any relationship to a community of that name, but remember seeing the sign while driving down to Mena once.
I have read some references to Dick Kitchens that were written in Fort Smith during the war. I'm not in Arkansas right now, but when I get back home next week I'll see if I can find them for you.
Best,
Dale
