Magdalena Berger's father-, and mother-in-law, Sigmund and Margita Berger with friends

These are my husband Ivan Berger's parents. The photo was taken on their family property in the village of Torda in Banat, Serbia. My father-in-law, Sigmund, is pictured standing on the left. Margita Berger, his wife, is seated between the two men. I don't know who they and the others are.
