My ggggrandfather Jacob Washburn was living in a hotel, listed as a welder in the Kenosha County federal census records of 1850. I believe that he was working on the building of the port of Kenosha at this time. His family is not listed with him. I have no idea if this is currently known as Southport. Is there a list of workers that worked on the port building? Where and how could I get more information on this?
