Saint Eudokia was born in 1879 in the village of Troparyovo in the Moscow province to a peasant family of Efrem Sinitsin. In her youth, she became a novice at the Prince Vladimir Monastery, established in memory of the salvation of Emperor Alexander III and his family during the railway disaster on October 17, 1888. The monastery was founded at the request of the lady-in-waiting Princess Vera Borisovna Svyatopolk-Chetvertinskaya, and permission for its establishment was granted on October 3, 1890. After the closure of the monastery in 1929, Eudokia settled in the village of Filimonki with a sick relative.
In early 1938, she was arrested on charges of anti-Soviet agitation and the distribution of religious literature. On February 25, 1938, she was arrested and imprisoned in the city of Serpukhov. On March 8, 1938, the NKVD troika sentenced her to death by shooting. Saint Eudokia was executed on March 20, 1938, and buried in a common unmarked grave at the Butovo firing range near Moscow.
