Great pic, I would guess it dates to about 1970.
It's been a very long time, and the sunglasses make it harder to recognize, but here's my best guess:
back row: #4 Melvin Mathews, #6 Ron Columbo, #7 Al Dennison
front row: #1 Pete MacKenzie, #2 Mark Daniels, and one of the adults must be Claire Schumaker.
Again, my best SWAG, and probably some mistaken IDs on my part. Jim Morway rings a faint bell. The Rudner brothers should be in the pic too, but my memory fails me...
