Thornhill baronets

There have been two baronetcies created for persons with the surname Thornhill, one in the Baronetage of England and one in the Baronetage of the United Kingdom. Both creations are extinct.

The Thornhill Baronetcy, of Olantigh in the County of Kent and of Barbados, was created in the Baronetage of England on 24 December 1682 for Timothy Thornhill, the member of an old Kentish family. He was childless and the title became extinct on his death in circa 1693.

The Thornhill, later Compton-Thornhill Baronetcy, of Riddlesworth Hall in the Parish of Riddlesworth in the County of Norfolk and of Pakenham Lodge in the Parish of Pakenham in the County of Suffolk, was created in the Baronetage of the United Kingdom on 11 August 1885.
