When I toured the Yussupov Palace in July 2005, we were shown a large portrait of Xenia Sfiris. It is in the room with the two beautiful stained glass windows. We were told that Xenia, the granddaughter of Felix and Irina, now has a granddaughter, presumably Marilia, and that she is the latest in the Yussopov line. I found it interesting that they had displayed this modern painting, which, by the way, is quite lovely.
