Romanov impostors

The members of the Russian imperial family, the House of Romanov, were executed by firing squad by the Bolsheviks in Yekaterinburg, Russia, on July 17, 1918, during both the Russian Civil War and near the end of the First World War.

Afterwards, a number of people came forward claiming to have survived the execution. All were impostors, as the skeletal remains of the Imperial family have since been recovered and identified through DNA testing. To this day, a number of people still falsely claim to be members of the Romanov family, often using false titles of nobility or royalty.

DNA testing
In 1991, human remains were found in the forest outside Yekaterinburg. They have been identified through DNA testing as belonging to the Romanovs and their servants. In 1998, the Romanovs were buried in St. Petersburg and have been declared passion bearers by the Russian Orthodox Church. However, two sets of remains were missing from the mass grave. Scientists identified the missing family members as Tsarevich Alexei Nikolaevich of Russia, who was a few weeks short of his fourteenth birthday at the time of the killing, and either Grand Duchess Anastasia Nikolaevna of Russia or Grand Duchess Maria Nikolaevna of Russia, who were seventeen and nineteen respectively at the time of the killings. The report of two missing bodies continued until the late 2000s to fuel speculation that one or more members of the family could have survived.

On August 23, 2007, a Russian archaeologist announced the discovery of two burned, partial skeletons at a bonfire site near Yekaterinburg that appeared to match the site described in Yurovsky's memoirs. The archaeologists said the bones are from a boy who was roughly between the ages of ten and thirteen years at the time of his death and of a young woman who was roughly between the ages of eighteen and twenty-three years old.  Along with the remains of the two bodies, archaeologists found "shards of a container of sulfuric acid, nails, metal strips from a wooden box, and bullets of various caliber." The bones were found using metal detectors and metal rods as probes. 

On January 22, 2008, Russian forensic scientists announced that preliminary testing indicated a "high degree of probability" that the remains belong to the Tsarevich Alexei and to one of his sisters. The Yekaterinburg region's chief forensic expert Nikolai Nevolin indicated the results will be compared against those obtained by foreign experts and a final report could be issued by April or May 2008. On April 30, 2008, Russian forensic scientists announced that DNA testing proves that the remains belong to the Tsarevich Alexei and to one of his sisters.  With this result, all of the Tsar's family are accounted for, proving that none of them survived the execution.  the Russian Orthodox Church has not yet recognized these remains as belonging to the imperial family; the House of Romanov has expressed openness to the possibility of having the remains exhumed for further analysis and confirmation of their identity.

Anastasia's survival stories have always been the most famous, inspiring dozens of books and films.

Anastasia impostors
Some of the women who claimed or were believed to be the Grand Duchess Anastasia Nikolaevna of Russia are:
 Anna Anderson, real name Franziska Schanzkowska, was, by far, the most famous impostor. She appeared in 1920 in Berlin, Germany, and died in Charlottesville, Virginia, in 1984; 
 Eugenia Smith, aka Eugenia Drabek Smetisko, appeared in Chicago in 1963, had a book published titled Autobiography of HIH Anastasia Nicholaevna of Russia that year, and died in Rhode Island in 1997.
 Eleonora Kruger, lived with George Zhudin and died in a Bulgarian village; 
 Natalya Bilikhodze, appeared in 1995 and went to Russia in 2000 to "claim the Romanov fortune." 
 Nadezhda Vasilyeva, appeared in the 1920s in Russia and died there in a Kazan psychiatric ward in 1971.

Alexei impostors
Several men who claimed to be Tsarevich Alexei Nikolaevich of Russia.
 Vasily Filatov, whose claim came from Astrakhan, Russia, shortly before his death in 1988.

 George Zhudin (????-1930), lived with Eleonora Kruger and died in a Bulgarian village;

 Heino Tammet, who died in 1977 in Vancouver, British Columbia, Canada.
 Michael Goleniewski, a CIA agent who in 1959 claimed to be the Tsarevich.
 Author, Michael Gray, (an alias adopted by a Northern Irish teacher) claimed in his book Blood Relative that the Tsarevich escaped with the Dowager Empress aboard the warship HMS Marlborough in 1919 and later assumed the name Nikolai Chebotarev. In the book, Gray claims he is the son of the Tsarevich and Princess Marina, Duchess of Kent, and they had secretly married in the late 1940s.
