Mariamne (born 34 or 35) was a daughter of King Herod Agrippa I. She was betrothed by her father to Julius Archelaus, son of 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.
