Hi - This may not be of much help, but I have a list that shows Emilie Auguste Loeber's siblings as Julius, Christine (b. March 1880), Augusta, Henry, and Emil. All children of August Loeber and Ottilie Doerr. You may also already know that Emilie Auguste Michaelis (Loeber) passed on 08/21/1944 in Stillwater, MN.
She would have also been my Great Grandmother - One of Carl and Emilie's children was Victor Karl Heinrich Michaelis - my paternal grandfather.
