Henry Pelham Pelham-Clinton was a British aristocrat and politician who inherited the Newcastle-under-Lyne dukedom in 1795 and controlled substantial estates and electoral interests, including Aldborough and Boroughbridge.

The source gives the sale to Andrew Lawson in 1834 but does not identify the prior Newcastle acquisition instrument.

Research sources:
- English Heritage, History of Aldborough Roman Site, stating that Aldborough was a valued possession of successive Dukes of Newcastle and that Andrew Lawson purchased Aldborough manor in 1834 from the 4th Duke of Newcastle; corroborated by the study 'A Great Electioneer and His Motives Reconsidered,' which identifies the Duke as lord of the manor of Aldborough. — https://www.english-heritage.org.uk/visit/places/aldborough-roman-site/history/
