One of the four or five noble families which, according to legend, were transported by Titus (70-81) from Jerusalem to Rome. The history of this family, however, can only be traced to the fourteenth century. In the fifteenth century the family seat was at Bologna. A notable representative of this family was Moses ben Judah Nagari. In the fourteenth and fifteenth centuries there were in Spain and in southern France families named Dels Infanz and Dels Fils, distinguished for wealth and learning. It is probable that they were connected with the Italian family Degli Adolescentoli.
