Jean Lidderdale Campbell has identified at least two of these photographs.

Looks Californian. Back of photo has “La Casa Del F...jo” [obscured by glue].

Jean Campbell: Junction City, Ohio. House closest to us is the Landrum house. Two houses up the hill is the Lidderdale house. See next picture.

Up close, I can see Arthur, Mildred, and other unrecognizable family members.

Jean thinks this might be the Hilbury house in Ft. Erie, Canada (near Niagara Falls).
