1910s Photo of my Grandfather's Baseball Team

I am trying to find out where I can research this teams history. All I know is what my dad told me. They played weekends and he got paid more for a weekend of baseball than he made in a months worth of work in the Wisconsin coal mines. The team was from Highland Wisconsin or somewhere close to there like the Dodgeville area which would have been within a reasonable day trip. I can't see too much further because traveling would have been difficult. If anyone could give me guidance on where I can look for information I would appeciate it.
