Ceclava Czapska
Ceclava Czapska was a Romanov impostor who claimed to be the Grand Duchess Maria, daughter of Tsar Nicholas II, the last autocratic ruler of Imperial Russia, and his wife Tsarina Alexandra.
She was the daughter of Polish nobleman, Bolesław Czapski and Raja Ludmilla Tchapline. On 20 January 1919, she and Prince Nikolai Dolgoruky, called 'di Fonz,' were married in Romania. They had two daughters, Olga-Béata, mother of Alexis Brimeyer; and Julia-Yolande.
She died in Rome. Her grave is in Prima Porta.
The remains off all the Romanovs have been found and identified via DNA testing disproving her claim.
