I am looking for information on Ida Kanis, who married a Roepke. They had two daughters, Bertha and Minnie, and probably lived in southeastern Wisconsin or northeastern Illinois (though it is possible she remained in Germany). She was born in Germany about 1850; her parents were John (Johann) and Augusta Kanis (they came to the U.S. about 1885). She had two brothers, John (Johann) and William (Wilhelm). I am trying to determine where in Germany she was born and where the family lived. Thank you for any help.
