Rav became closely related, through the marriage of one of his daughters, to the family of the exilarch. Her sons, Mar Ukba and Nehemiah, were considered types of the highest aristocracy. Rav had many sons, several of whom are mentioned in the Talmud, the most distinguished being the eldest, Chiyya. Chiyya did not, however, succeed his father as head of the academy: this post fell to Rav's disciple Rav Huna. Two of his grandsons occupied in succession the office of exilarch.
