Reck, Feldmiller, Debus family members

Photo found at flea market (oregon). Not my family line.
Front of pictures has some names, also clarified a little bit on back of picture.

After a little research, I believe this is possibly:

Carlyle Reck, gma Reck, John C. Debus, Eva Catherine (Feldmiller) Debus and Libby (Feldmiller) Reck.
Picture has written: Oil City, PA.
Many in this family were born in New York, lived in Venango co., PA and later in California.
