In Hohengehren, Wirttenberg, Germany, Jakob Koch was born January 23, 1804. He married Regina Catherina Kiesel on February l7, 1829. (She was born March 30, 1804). They had a son Johannes born January 3, 1830. I have a list of his descendants. I wonder if Jakob and Regina Catherina had other children? My ancestor is Elizabeth Koch Heinen who died December 25, 1891 in Mitchell County Kansas. I am trying to find her parents. Any help out there? Thank you. Kay Thull
