"Uncle James Damon and Ralph" (caption from top of photo)
Uncle James would be Uncle to Melissa Larsen (Trezise). Ralph is the young boy leaning on him. They are in front of a porch and house, and another house along with a fenceline can be seen behind them.
From left to right: Duane Larsen, Hester Larsen, & Hans Larsen. Mother & Daddy Figgins are on the right side of the photo. They appear to be at the Larsen's ranch.
