Ran across your postings, I have a Augusta or Auguste Dehn aka Daehne born 10 Aug 1836 died 17 Jan 1916 in McLeod county MN. She married Frederick Schimmel and had the following children Augusta, Marie, Charles, William, Wilhemine, Ernest, and Elizabeth (not sure of order of the older children). The family immigrated in 1884 on the ship Braunschweig, leaving from Bremen and arriving in Baltimore. Not sure where in Germany they came from, but have info that Frederick Schimmel may have been from Falkenburg. Frederick's brother John stated he has from Trampe, Brandenburg and another researcher suggested that they were from Neuruppin, Brandenburg. I don't know much about German geography, should look for a map to see if the areas listed are even close to each other!
