Hersilia

In Roman mythology, Hersilia was the wife of Romulus, the founder and first King of Rome. She is described as such in both Livy and Plutarch; but in Dionysius, Macrobius, and another tradition recorded by Plutarch, she was instead the wife of Hostus Hostilius, a Roman champion at the time of Romulus. This would make her the grandmother of Tullus Hostilius, the fourth king of Rome.
