AR online indexes have not been kind to me. But I did stumble upon a 1936 marriage record for him and Tressie Pettigrew in Union, Pulaski, AR. Tressie died in Springfield, Sangamon, IL.

By dingy, I think this is him in the AR Death Index:

James Nation
Death Day: 3
Death Month: Nov
Death Year: 1938
County: Pulaski
Roll Number: 19341940
Page Number: 2540

Thanks, Regina, for prodding me to look again. I'll send for this record pronto!

BTW, I am waiting for my dad's delayed birth certificate in AR.
