Elke....
I'm from south Chicago , Harvey to be exact. My father was also Alex Brandenburg.
My uncle was Herman Brandenburg,1877-1919, married to Wilhelminne Embacher,1876-1939.
My aunt was Johanna Brandenburg,1880-1962,married to John Lewis Karlovsky, ?-1935.
Herman Wilhelminne had 4 children:
John br.1902
Joseph br. 1905
Frederick br. 1907
William br. 1910 ( changed his last name to Brandt)


Any connection here?
