Marcus Volturi

Marcus Volturi is a co-leader of the Volturi and Aro's brother-in-law in the Twilight saga. He has the ability to sense the nature and strength of relationships. In the human world, he is revered as "Saint Marcus", a holy priest who drove vampires out of Volterra. The Volterra people celebrate St. Marcus Day on March 19th each year. The legend likely arose from the Volturi's prohibition of hunting within Volterra's walls. His wife, Didyme, was killed by her brother, Aro, and he has been living without her ever since, feeling empty and depressed, according to various fan forums. His ability to see the emotional ties between people, which is valuable to the Volturi, is a constant reminder of his own lack of connection
