This reminds me--allegedly sometime after the murders of the Imperial Family, someone started a pretty lucrative scam regarding "escaped" Grand Duchesses and ships.
They hired a young prostitute who bore a marked resemblance to Grand Duchess Tatiana, dressed her up in "Imperial fashion", and would escort her on board a docked ship with great pomp, claiming that this was in fact Tatiana, that she had escaped, and was boarding the ship on her way to safety out of Russia. Apparently for a fee people had the "honor" of being introduced to the "Grand Duchess", and apparently quite a few people fell for it.
What they didn't know--aside from the fact that she was a prostitute and definitely not a Romanov, much less Tatiana---was that the girl would board the ship, put on her little pretense, and then secretly get off the ship before it set sail.
As I recall this little group of pretenders were eventually nabbed by the cops, thus putting an end to the charade.
I wonder how many honest (if gullible) people went to their graves swearing that they had actually met and spoken to Grand Duchess Tatiana aboard a ship long years before??
