Larisa Fyodorovna Tudor (June 10, 1897 - July 18, 1926) remains a mysterious figure, having passed away at the age of 29. There is a theory that she could have been Tatiana Romanova, the second daughter of Russian Emperor Nicholas II, who miraculously escaped the fate of her family (see the book "The Romanov Conspiracies" by Michael Ockleford, London, 1993).

Little is known about Larisa Tudor. Her marriage certificate to Owen Tudor lists her name as Larisa Hauck, with her father named as Adolf Hauck, which does not match the inscription on her gravestone, where her father is mentioned as Fyodor. The death certificate states that she died of heart failure caused by tuberculosis of the spine and lungs.

There are several theories about her origins. One suggests she was a belly dancer in a nightclub in Constantinople and the daughter of a butcher. Another theory claims she came from an aristocratic family in St. Petersburg, Russia.

After her death, her husband received a significant sum of money, equivalent to two years' salary of a soldier. Many believed that this money was obtained from funds that Larisa's father had hidden in foreign banks for his daughters.

More than 60 years later, neighbors, upon seeing photographs of Grand Duchess Tatiana, immediately recognized her as the woman they knew as Larisa Tudor.
