I have information and old family letters that may answer some questions. My link to your family is through my great-great-aunt Annie MISCHLEWESKI who married (Johann) Carl arndt in Queensland. Carl and Annie first raised cattle and then had milk cows (don't know if they were also still raining beef). I have family letters from Queensland to Missouri in the US from 1898 to 1912 that I have transcribed.
