After the overthrow of King Zedekiah of the House of David his lineage was carried on by the Exilarchs.Descendants of the house of exilarchs were living in various places long after the office became extinct. A descendant of Hezekiah, Hiyya al-Daudi, Gaon of Andalucia, died in 1154 in Castile according to Abraham ibn Daud. 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, Benveniste, Hajj Yachya and Ben-David. One tradition also traces the ancestry of Judah Loew ben Bezalel to Babylonian Exilarchs (during the era of the geonim) and therefore also from the Davidic dynasty, which is however disputed. According to another tradition, Rabbi Elazar Rokeach of Amsterdam of the Belz (Hasidic dynasty) was a descendent from the house of King David. Another Rabbanic Dynasty Charlap also are reportably from the House of King David.
