I am looking for any information regarding the following HACKERS: Joseph, b. before 1850, Fredrick b.Aug 1858, Helmuth August b.1865 Harry b. 1891. There is also Minnie, Marie, and Hazel unknown birthdate. Joseph HACKER married Mary COOHON. She was born in Germany also. The above lived in St. Joseph Co., MI. I only know that they came to the US after Harry was born. If this sounds like any of your family please e-mail me ASAP. I hit a big brick wall.
