I have some of my own unidentified photos, two of which may look like similar subjects as yours. You may find them here:
They are photos #1&2. The boys may look similar, particularly that the smaller boy has a white spot on his left lapel area - same as on your photo (I used the utility "Magnifier" on my computer to see it). Also, the house siding/trim looks similar on both. The trees in mine are not white but maybe my photo was taken a little later after the sun came out. Just a thought.
