The earl of Southesk also holds the Scottish feudal title of Baron of Kinnaird and is a baronet in the Baronetage of Nova Scotia.

The representation of the family then passed to his third cousin Sir James Carnegie, 3rd Baronet, of Pittarrow (now recognized as the de jure sixth earl of Southesk; for earlier history of the baronetcy, see below).

His son, the fourth baronet and de jure seventh earl, also represented this constituency in the House of Commons.

His son, the fifth baronet and de jure eighth earl, briefly represented Aberdeen in Parliament.

His grandson, the eleventh earl, married Princess Maud, granddaughter of King Edward VII.
