I am studying the Jansen family who have roots in Effingham County, Illinois. Anton B. Jansen arrived with his parents and married Elizabeth Brummer in 1842. They had a large family which included my g-g-grandmother Anna Helena Jansen, who married Joseph L. Schmidt. After Anna's death, Joseph married her sister Melania.
I am trying to document the Jansen/Brummer marriage. I am also studying the other children in this family and trying to follow their lines.
