Aelia Sophia was the Empress consort of Justin II of the Byzantine Empire from 565 to 578.According to the Ecclesiastic History of John of Ephesus, Sophia was a niece of Theodora, the Empress consort of Justinian I. John of Ephesus did not specify the identities of her parents. According to the Secret History of Procopius, Theodora had only two siblings: her older sister Comito and younger sister Anastasia; either one could be the mother of Sophia. Procopius identifies Comito as a leading hetaera of her age. John Malalas records that Comito (b. ca 500) married general Sittas in 528. Sittas may thus be the father of Sophia. Whether Anastasia ever married is unknown.
