Wisconsin had a mid-decade census in 1895. Otto is listed on the left side, 12th down.
The census doesn't list the other household members by name, but does indicate there were 4 males and 3 females living in the home. It also indicates 4 were born in Germany and 3 were born in the United States.
The 1910 US Federal Census indicated that Otto and Hulda had 2 children, Otto Jr and Martha, so it's difficult to determine who were the other 3 residents of the household - family members, boarders or laborers.
I am presently searching for Paul Junghans' record, but there are several pages to go through. If I find it, I'll post it.
