A great uncle on Svetlana 's mother 's side , Efim Dreizer , was a victim of the Great Terror of the 1930s . He was arrested , confessed under duress , tried in the first Moscow show trial in 1936 and executed for purportedly participating in a criminal plot in the Red Army directed by Leon Trotsky . His family were treated harshly as the family of a so-called " enemy of the people " and met death and exile during the terror . They were " rehabilitated " ( restored to full citizenship rights ) during Khrushchev 's " Thaw " of 1956-1958 ; Efim Dreizer was posthumously rehabilitated only in 1988 , during Gorbachev 's Glasnost campaign
