The title Baron Howard of Glossop was created for a younger son of the 13th Duke of Norfolk in the Peerage of the United Kingdom in 1869. The death of the last Viscount Fitzalan of Derwent made the Barons Howard of Glossop next in seniority to the Dukes in the Howard family. As the 16th Duke of Norfolk had no sons, all his titles that could pass only to heirs male descended to the 4th Baron Howard of Glossop when he died in 1975. The new Duke of Norfolk had already inherited the title of Baron Beaumont from his mother the year before inheriting the Howard of Glossop barony from his father. The Barony of Howard of Glossop is therefore now a subsidiary title of the Dukes of Norfolk.
