I am looking for the family of Anna Ahrens in the 1870 and 1880 US Census in Brooklyn, NY. Anna came from Germany in 1869. I believe she was married and had at least one son. She is listed in the 1900 census as a 56 year old widow with one living child. She was supposedly born in 1844. I am trying to track Anna's life in America. I believe she married a Mr. Mollenhauer between 1900 and 1907. And then Dietrich Hinsch in 1907.
