unknowns - kind of ...

This is written on the back of this particular photo. James Benjamin Daigle was my great grandfather, and I do know that when he built the house on 4500 Perry Street in Denver, that the Gilliand brothers are the men who built the china cabinet that graced Grandma's dining room. They actually built the china cabinet right into the walls, so we were unable to have it removed intact before the house was demolished. So, perhaps one of these gentlemen is Jack Cook and the other, Columbus Gilliland. Grandma's house was built circa 1898-1900. Anyone have ideas on what kind of uniform the man in the front of the photo is wearing?
