Helena of Constantinople

Saint Helena of Constantinople (248/250-328 CE) was the mother of Roman emperor Constantine I (r. 306-337 CE). She famously made a pilgrimage to Jerusalem where tradition claims found Christ's true cross and built the Basilica of the Holy Sepulcher. She is venerated as a saint and considered the patron of archaeologists, converts, difficult marriages, divorced people, empresses, Saint Helena Island, and new discoveries.
