Tatiana comes from the Latin Tatianus, the feminine of Tatianus, derived from Titus or possibly the Sabine king Titus Tatius. Saint Tatiana, a 3rd-century Christian martyr in Rome, gave her name to all subsequent Tatianas.
Tatiana is among the most popular girl names in Russia and across Eastern Europe. Pushkin's verse novel Eugene Onegin features a famous Tatiana. Today it sits in the U.S. top 350.
Tatiana reduces to two — the number of grace and partnership.
