When a person was leaving historical areas that became Germany, they were often legally obligated to get permission. This differed by time and place. Usually, nineteenth century migrants were under some obligation to register. The requirements generally ensured people paid their debts and men had fulfilled their military obligations. Not everyone abided by these laws. Good statistics are hard to find, but in my own experience, way less than half of emigrants went through this process. But when they did, records were created! I am going to show you an example today.
My great great grandmother, Katharina Ohnemus, received permission to emigrate in June 1854. She was leaving Schweighausen, Freiburg, Baden [today’s Schweighausen-Schuttertal in Baden-Württemberg]. Her emigration document [Auswanderungsakte] contains five pages and is full of good details.[1] She was nineteen years old, unmarried, and she planned to travel with her sister. Her parents were Protas Ohnemus and Franziska Offenburger.
She indicated that she had enough money for the trip. She intended to travel via France to New Orleans. Katharina and her parents’ signatures are all included.
I have never found her immigration record at New Orleans. Shortly after she arrived, she married Landolin Meyer who was also from Schweighausen.[2] I have not found his emigration record.
Next week, I will show you how I found and ordered this record.
