Unknown young couple

4 x 6 sepia tone portrait of a young couple. Perhaps an engagement photo, as rings are evident on woman's hand. Probably taken 1930's - 1940's.

This was found among the effects of Elois Turner Humble in Lamont, CA. Elois's parents were Charles and Atha Turner, she had 6 siblings, and the family lived in Nowata, OK in the 1930's. Believe though, that this could be someone in the family of Elois's step-father, Corwin Walker, born 1891 died 1966 Ventura, CA or in the family of Elois's 2nd husband, Ray Buchwitz, of CA.
