Barbara Yakovleva was a Russian nun born around 1880 in Tver. After working as a maid for Grand Duchess Elizabeth Fyodorovna, she entered the Martha and Mary Convent in 1910. During the political upheavals of 1917, she remained loyal to the Grand Duchess, accompanying her into exile. Her life ended tragically in 1918 when she was captured by Bolshevik forces. She is honored as a venerable martyr within both Catholic and Orthodox traditions for her steadfast faith and service.
