Here is the 1930 US Census for my great grandfather, Paul Richard Junghans. Paul was living at the home of his son, Paul Jr and wife Rosina and their son Richard in Jefferson County near Fort Atkinson, Wisconsin.
Also living in the household was Paul Richard Junghans' sister-in-law, Mary Schmidt.
Like so many census records with errors, this one indicates Paul Richard Junghans immigrated to the United States in 1868. As I pointed out in earlier posts, he immigrated sometime in 1886.
