Yehuda Leib Rokeach/Margolioth Rokeach or Margolioth

The addition of Yehuda Leib is based on research by Hadassah Lipsius who found that the Otsar HaRabbanim lists Rabbi Yehuda Leib Margolies of Kozienice as the grandson of Baal Maaseh Rokeach of Amsterdam and son-in-law of Rabbi Moshe of Kurow, son of Rabbi Avram Abyush of Frankfurt. There are inconsistencies in the record on this connection, but only as to the date of death of Yehuda Leib of Kozienice and the relationship of Moshe of Kurow to Avram of Frankfurt..
