Looking for information on my maternal ancestry. They were German farmer-settlers to this area from around 1800, until their forcible resettlement during the 1930's Soviet collectivisation of private farmlands. Family members were separated, some sent to Siberia and other more eastern parts of the former USSR, others remaining in the Kherson or Zaporizhia areas until WW11, when they transferred to Germany. Most of the latter group now live in the USA or Australia.
Any information about these families, and the present day name and livelihood of Rosalienfeld, and the former nearby settlements of Marienfeld and Kronstadt, would be most appreciated.
