of the house of exilarchs were living in various places long after the office became extinct. The grandson of Hezekiah ben David through his eldest son David ben Chyzkia, Hiyya al-Daudi, died in 1154 in Castile according to Abraham ibn Daud and is the ancestor of the ibn Yahya family. Several families, as late as the 14th century, traced their descent back to Josiah, the brother of David ben Zakkai who had been banished to Chorasan (see the genealogies in [Lazarus 1890] pp. 180 et seq.). The descendants of the Karaite Exilarchs have been referred to above. A number of Jewish families in the Iberian peninsula and within Mesopotamia continued to preserve the tradition of descent from Exilarchs in the Late Middle Ages, including the families of Abravanel, ibn Yahya and Ben-David. Several Ashkenazi scholars also claimed descent from King David. On his father's side, Rashi has been claimed to be a 33rd-generation descendant of Johanan HaSandlar, who was a fourth-generation descendant of Gamaliel, who was reputedly descended from the Davidic line. Similarly Maimonides claimed 37 generations between him and Simeon ben Judah ha-Nasi, who was also a fourth-generation descendant of Gamaliel. Meir Perels traced the ancestry of Judah Loew ben Bezalel to the Hai Gaon through Judah Loew's alleged great-great-grandfather Judah Leib the Elder and therefore also from the Davidic dynasty; however, this claim is widely disputed, by many scholars such as Otto Muneles. Hai Gaon was the son of Sherira Gaon, who claimed descent from Rabbah b. Abuha, who belonged to the family of the exilarch, thereby claiming descent from the Davidic line. Sherira's son-in-law was Elijah ben Menahem HaZaken. The patriarch of the Meisels family, Yitskhak Eizik Meisels, was an alleged 10th generation descendant of the Exilarch, Mar Ukba. The Berduga family of Meknes claim paternal descent from the Exilarch, Bostanai. The Jewish banking family Louis Cahen d'Anvers claimed descent from the Davidic Line Rabbi Yosef Dayan, who is a modern-day claimant to the Davidic throne in Israel and the founder of the Monarchist party Malchut Israel, descends from the Dayan family of Aleppo, who paternally descend from Hasan ben Zakkai, the younger brother of the Exilarch David I (d. 940). One of Hasan's descendants Solomon ben Azariah ha-Nasi settled in Aleppo were the family became Dayan's (judges) of the city and thus adopted the surname Dayan.
