I'm not a family member but saw a group of photographs in an antique mall in Knightstown, Indiana, and there were very good genealogical notes written on the backs so I bought them in hopes of helping someone. I think I have a picture of your grandparents. The back of the pictures has written:
Uncle Jim and Aunt Callie Upthegrove Uncle Jim died 1948 Aunt Callie died 1940 Berne, Indiana
The photos seem to have belonged to a Gladys Casey.
I'm in touch with someone who is a Casey, and we will be meeting soon to sort out the photos. Feel free to contact me: firstname.lastname@example.org
