In 1850 census, there is a John H. Schlichte, age 70, born in Germany, living with his daughter and son-in-law, Joseph and Ann Mary Vorwald (AKA Forwald) in Newport Township, Johnson Co, Iowa. Next door is Joseph's brother, Francis Vorwald and family. Shortly after 1850, Francis and family moves to New Vienna, Iowa. I wonder if there is any connection to your Schlichte family. Joseph and Ann Mary were my g-g-g-grandparents.
