looking into my great grandfather's origin (Georgi Oduzengko) and seeking some assistance. he left odeska during or shortly after the end of the russian revolution - he told his daughters he used to be an officer of the tsar's army / navy and fought with the whites. he migrated to greece - still looking into the exact date. His mother and sister supposingly became nuns in Romania.
i am not sure about the spelling of his surname - Oduzengko or Oduzengkou according to my grandmother's identity (translated from Greek characters).
any help or guidance would be much appreciated.
