Mariamne (born 34 or 35) was a king's daughter of King Agrippa I of ancient Roman Judea and Cypros. She was the paternal granddaughter of Aristobulus IV, and great-granddaughter of Herod the Great and Mariamne (Hasmonean Branch).
She was betrothed by her father to Julius Archelaus, son of Helcias/Chelcias (maybe Hilkiya in Hebrew who was a friend and an officer at the court), [1] but this marriage had not yet been enacted upon her father's death. Her brother Agrippa II enacted the marriage once he had been made tetrarch in around 49/50. From this marriage was derived a daughter, whose name was Berenice.
Around 65 she left her husband and married Demetrius of Alexandria who was its alabarch and had a son from him named Agrippinus. [2]
