The title of Earl of Dunbar was resurrected in 1605 for George Home, 1st Lord Hume of Berwick, Chancellor of the Exchequer, and his heirs male. This title became dormant only six years after its creation, upon Home's death in 1611. Some of his kinsmen were said to be acknowledged as de jure holders of the title, but none of them ever appears to have assumed the title.
Note: No claimant has progressed his claim before the House of Lords Committee for Privileges to a satisfactory conclusion. This Committee was - until the Dissolution of Parliament on 12 April 2010 - the only body which was authorised to decide whether or not a claimant may be confirmed in the title. The Lord Advocate of Scotland, for instance, has no authority in these matters, especially in the 17th century, given the corruption and nepotism rampant at that time. The usual way to establish the right to inherit a title is to apply for a Writ of Summons to attend Parliament (a procedure that will have to be reviewed in the light of new legislation abolishing the hereditary parliamentary rights of peers). Then the Committee for Privileges examines the validity of the documentation supporting the line of descent of the claimant and his relationship to the previous holder of the peerage title.
In 1721 James Murray (c.1690–1770), second son of David Murray, 5th Viscount of Stormont, was created Earl of Dunbar, Viscount of Drumcairn and Lord of Hadykes in the Jacobite Peerage by James Francis Edward Stuart, the "Old Pretender".
