This is a photo of a part of my family, which emigrated from Germany to America in 1870. They settled down in Jefferson County. The photo is made in Madison. They are Catharina Hirtz, born 1817, my great-great grandmother and her three sons: Michael, born 3.6.1846, Andreas, born 19.10.1844, Johann Nikolas, born 31.5.1848. I seek their descendants.
