In Tracy, Minnesota, Victor and Jenny Holm (back row left). Standing next to Victor and Jenny are Blenda (Anderson) Nordstrom, Elizabeth (Longstrom) Weidauer, and Agnes (Almhjeld) Longstrom. Seated in from of Victor is his uncle Otto Holm and Ottos wife Caroline (Anderson) Holm, Emelia (Anderson) Longstrom, and Victors cousin Gustav Longstrom. Sitting on the ground are Karen and Carol Weidauer. Evidence that this photo was taken in August 1948 is that Victor sent his daughter Aurora a postcard from Tracy on 1948 Aug 20. Additional evidence is that Victor wrote in his memoir that he saw Otto in 1948.
Gustav Longstrom was the son of Ottos sister Anna Maja Långström. He immigrated to America in 1893.
Here is Victors identification on the back of this photo. I translated this as Tracy. Uncle and aunt, cousin Gustav and his wife. His two daughters to the right and grandchildren in front.
