It is possible that Menshikov, who was quite jealous of Peter's attentions and knew his tastes, wanted to procure a mistress on whom he could rely. In any case, in 1703, while visiting Menshikov at his home, Peter met Marta. In 1704, she was well established in the Tsar's household as his mistress, and gave birth to a son, Peter. In 1705, she converted to Orthodoxy and took the new name of Catherine Alexeyevna ("Yekaterina Alexeyevna"). She and Darya Menshikova accompanied Peter and Menshikov on their military excursions.
