I'm looking for information on Katharina Klahsen b. 1889 in Germany, d. 1925. She married Heinrich Haller b. 1886 in Stolberg-Dorff, Germany, d. 1971 in Ohio. They had 2 daughters: Katharina Hubertina Haller (my grandma, b. May 11, 1911 Germany, d. December 18, 2006 FL) and Emma Rosalia Haller (b. 1916 Germany, d. before 1947 Germany). I don't have any further information on Katharina Klahsen. I'm looking for her parents, siblings, or anything relevant to her life. Thanks!
