When my grandfather's family immigrated to the US about 1915 from Lithuania, many of his aunts, uncles, cousins stayed in what was then Russia, now Lithuania and Germany a some decades earlier. His mother, Augusta Pauline DuBois(wife of Julius Daniel Konradt), though of French Huguenot descent, spoke German at home. I know that she had brothers, sisters & cousins who stayed in the region of Kelme (Raseiniai) I found the grandson of one long lost cousin who settled in Uruguay after/or during WWII, but I know that there must be more out there. Please respond if your DuBois or Konrad family was from this region. THank you!
