3 Unknown Men

A photo of three unknown men. All I can state is that this picture was found at my grandmother's house after she passed away......Would love to learn more about who they are and how they could possibly be related to my mother and me. The picture was taken during the time of 1898 - 1906 .....that is approximately the time of Wagner Studio in Pueblo, CO

Who are these men?
Are you related to any of these men?
