This photograph was in a pocket sized photo album belonging to my grandfather. My aunt wrote on the back of the photo that it is the wife and children of her father's brother Ivan Papp in Satu Mare (now Romania). So far I have not discovered their names, but I see a clear family resemblance in the children.
I am woefully bad at dating photographs. These seem to be 1940s or early 1950s fashions. I would love to know if these were post or pre WWII.
