I warn all of you about "A Russian Princess Remembers." I was told by Prince Alexis Scherbatow who ran the Russian Nobillity Association for many years, that the so-called Princess Meshcherskaya was not, in fact a member of that family at all. Her book is also riddled with errors. There is, in particular, a photograph of her standing in front of the ruins of the house she claims was her family's palace (I believe she called it Doughino?.)
It is, in fact, the ruins of Petrovskoe-Alabino, which belonged to the Princes Demidov, and then the Princes Gagarin.
