I am looking for my ggg-grandmother, Mary Falkenstein, b. 10 May 1835 in Wurtemberg, Germany and d. 11 Oct 1893 in Plymouth County, Iowa. She married Abraham Jung at an unknown date and location. They had 5 children: Katherina, Maria Margaretha, Johann Abraham, Emilie, and Margaretha. My line comes through Katherina. I don't know anything about Mary's parents or siblings. I am also interested in descendants of Abraham and Mary's.
