Your pictures do not say what state or country they are in, but I know a person with surname Orr. She was my bridesmaid in Linden, Michigan 47 years ago. She still lives in Linden.
I do not know when this was taken, but i think it was taken in Iron County, Missouri, USA in the 40's. i would like to compare notes about the Orr's. feel free to contact me at [contact link]. thanks, mike
