Manrique were one of major Spanish aristocratic families of the Jewish converso descent. See, Norman Roth, "Conversos, Inquisition, and the Expulsion of the Jews from Spain", Madison, WI: The University of Wisconcin Press, 1995, p. 333. Jorge Manrique was a great-nephew of Iñigo López de Mendoza (marquess of Santillana), a descendant of Pero López de Ayala, chancellor of Castile, and a nephew of Gómez Manrique, "corregidor" of Toledo, all important poets of the late fourteenth and fifteenth centuries. He was, therefore, a member of a noble family of great consequence.
