Hi, I am trying to research my father's family line. They were of German descent, living in the Lodz, Poland area during WWII. My Opa was Richard Nikolai, my Oma was Helene Steidel. They had three children; Vera, Richard and Waldemar. My GrossOpa was Karl Nikolai and he married Wanda (unknown surname). Please contact me or post here if you have any information about this family. Thank you!
