How to find information on a business in the late 1800s to early 1900s. It is no longer in business.
My gr grandpa had a creamery business in New Berlin, Illinois. He sold it in the early 1900s. I cannot find any records of in but in a dairy paper with the name only. Where can I go to find information on it? I have no idea where to start. Name was West Sangamon Creamery. There is a clip from an old newspaper showing he was selling it.
Any idea where I could look?
