Miller's ranch, Colorado

A photo of Miller's ranch in Colorado - people unknown. One of the three photos I have associated to the Miller's ranch (in this set of photos), I do not know if these folks are Miller family or ? estimated time frame 1906 - 1915. Colorado Brand association indicated there was a Miller's ranch near Watkins, Colorado, and that would be reasonable, since the Bar T was there, and this photo was From Callie Ballard.

If you recognize anyone, holler, loud.
