Nina's daughter Marina Koshetz (also known as Marina Schubert)
"Known as"? Nina was married to Alexander von Schubert (about whom something needs to be added) and Marina was their legitimate daughter. Also, something should be said about Nina's long-time romantic attachment to Serge Prokofiev and her rivalry with Serge's wife, Lina. --Michael K SmithTalk 13:09, 20 October 2012 (UTC)
