Earl of Devonshire

The title of Earl of Devonshire has been created twice in the Peerage of England, firstly in 1603 for the Blount family¹ and then recreated in 1618 for the Cavendish family,² in whose possession the earldom remains.

It is not to be confused with, and is separate from, the more ancient title of Earl of Devon which belongs to the Courtenay family.
