She had one sister, Antiochis, who mothered Attalus I of Pergamon. Her father, Achaeus, was the second son of King Seleucus I Nicator and his first wife, Apama I. Her name implies a strong Seleucid connection, as she was the namesake of her paternal aunt and her paternal great grandmother of this name.
