Fetherstonhaugh baronets should not be confused with Fanshawe baronets.
The Fetherstonhaugh baronetcy, of Fetherstonhaugh in the County of Northumberland, was a title in the Baronetage of Great Britain. It was created on 3 January 1747 for Matthew Fetherstonhaugh, of Featherstone Castle, Northumberland, and of Uppark, Sussex, later Member of Parliament for Morpeth and Portsmouth. He had previously succeeded to the estates of his kinsman, Sir Henry Fetherston, 2nd Baronet (see Fetherston baronets).
He was succeeded by his minor son, Henry Fetherstonhaugh (known as Harry). The second Baronet also became Member of Parliament for Portsmouth—from 1782 to 1796, although never once speaking in the House of Commons. Indeed, he has been described as a "witless playboy". The title became extinct on his death in 1846.
The family surname was pronounced "fan-shaw".
