Looking for information on descendants of Carl Fredric Wilhelm Zimmerman b 1811 Bramstadt, or Heinrickshohe Neustettin, Germany; who were born between 1865 an 1890 who immigrated to Saskatchewan, Canada, Lake Fremont, Minnesota which became Zimmerman MN, and or South Africa who emigrated in or around 1892.

Have found traces of descendants still living in Germany with other family names. Any help is much appreciated.
