Frank Tessmann (b.abt 1838 in Prussia/carpenter), and wife Lena, (b.abt 1841 in NY) are listed in the 1880 Census, residing in Portage with two children, Frank (b. 1872 in Wisconsin--it appears Lena was his step-mother) and Minnie (b. 1878 in Wisconsin). My direct line
comes through Frank Jr. who later headed west to Utah and Nevada and was a house painter. I am looking for any additional info on this family.
