I can help you with the birthplace of Natalie and Carl. Natalie was born 20 Jun 1889 and Carl was born 24 Oct 1892, both in Kiselowka, Volhynia - then in Russia. The parents were Theodor Fandrich and Justine Noerenberg (sometimes Nerenberg or Nehrenberg). Between the world wars, the west part of Volhynia (including Kiselowka) belonged to Poland. After 1945 it was again in Russia, and later in the Ukraine SSR. Now Volhynia is in the northwest corner of Ukraine, next to the Polish and Belarus borders. See
