My great-grandfather is Frederick Charles Hardt who was born in Germany (Barmen, I believe) in 1867 and later (~1885) immigrated to America and settled in Chicago. His father was Karl Frederick Hardt, born Nov 19, 1934 in Lennep, Germany. Other children of Karl Hardt are: Karl F. Hardt (known in America as Charles F. Hardt) b. 1865 in Barmen, Germany, immigrated to the US in 1881. Rudolph Hardt - born in Germany, came to Chicago, moved to California Alexander Hardt - lived in Hagen-Haspe, Germany Albert Hardt - b. 1873, remained in Germany Johanna Hardt - b. 1879 Ludwig Hardt - b. 1881 I have more details on each of their children. If it looks like there's a link between us, I'd love to share our information. Carla Raabe Tibbitts
